I spent a few hours out tonight looking at NGC2264, M44, M41, M48, M46, M47, Saturn, the Double Cluster in Persus, and the Orion Nebula. All fit in the field of view at the lowest Power x Switch setting in my Televue 85. The Orion Nebula was incredible at the highest mag setting, and at the lowest setting I could still see the four stars of the trapezium - but could also see the full "sword" area. Just wonderful! -Mark Schultz, Illinois Russ: The Denk II Universal Power x Switch Package with D21s will cause me to lose sleep and my job if I'm careful! Very nice view of Saturn tonight before clouds rolled in...great job! Take care, -Jerry I LOVE the D21's! I got in two nights of viewing. Last night I was 4 hours in freezing 0 degree weather. The 21's are so good, I couldn't feel my toes anymore, but just had to stay out viewing. They are an excellent product. The 14's will be just as awesome, I'm sure. Thank you for such great products, sure makes it all worth it with the views. -Brian Schilt Dear Russ, Blake here, I won the binoviewers at the 2004 Black Forest Star Party. Anyways here goes: I don't own a scope at the moment but me and my buddy Chad have access to the 16 inch Meade equatorial Newtonian which is housed in the Observatory at the camp Susque Christian youth camp located in nice dark skies of Trout Run, PA. Camp Susque is located far enough from the skyglow of the nearby city of Williamsport that the views are really nice. I have to admit I am cheap! I was so anxious to use the binoviewers that I purchased two 17 mm erfles from Apogee Inc, and so the adventure began. It was a cold night in December and the sky was crystal clear almost perfect seeing, but it was so cold the observing list was short and the drive motors on the scope and hand controller were about frozen. First, we took a gander at Alberio; the colors of the blue and gold were rad! Next it was on to the Dumbbell Nebula (M27). It was as if Chad and I were in orbit around it. Then we went on to Saturn and it was awesome, but the most stunning and last object observed was M42, The Orion Nebula. It was unreal and with the power switch, we went from a nice view of the nebula to being inside the nebula. The Trapezium and the swirls of gas were eye candy. Keep up the excellent work. You make a wonderful product and I am hooked on binoviewing for life and my buddy Chad agrees. Cheers -Blake A. Ruth Hi Russ, I was able to pick a gap in the jet stream last night and get some pretty good seeing conditions for Saturn observation and have been blown away with the additional contrast bino viewing provides. I have frankly never seen as much extended detail with my 7" MCT on the globe as consistantly and with as much ease, absolutely stunning! Thought you would be interested in what kind of focal length increase I appear to be getting with a combo of an Intes Micro M715DX / SCT2 Mercury Systems SCT to 2" adapter / Televue 2" Everbrite / Denk Standard and various eyepieces. I did a couple of drift tests on three eyepieces with the powerswitch in and out. No, I was not wasting the good seeing - a front of clouds came through for an hour but I could still see Saturn through them albeit not very bright so I decided to do the tests while waiting for them to clear :)The M715DX focal length is quoted at 2700mm. I'm a little confused by the Nagler result as it appears to be close to parfocal with the 10mm TMB, any thoughts on that one? 13mm Nagler T6 focal length increase to 3357mm (+24%) and decrease to 1963mm (0.58 reduction). 12mm TMB Supermono focal length increase to 3077mm (+14%) and decrease to 1689mm (0.55 reduction) 10mm TMB Supermono focal length increase to 3122mm (+16%) and decrease to 1795mm (0.57 reduction) I am planning in the future to get a set of 14mm TMB's so with the +14% increase and 0.55 reduction applied to the three TMB's I will have power to aperture ratios from 17 through 44 evenly spaced - very sweet for planetary views. Cheers and interested in your thoughts on the Nagler situation. -David From; Jon Risch, Glencoe Minn. I have only had a couple chances to really use it to date as our weather for viewing hasn't been too good yet. Since I just wrote a check for it to the credit card folks for it, I don't think you will be getting it back! I am too much of a beginner to really evaluate it or compare it to anything else but I do like it. (Because I have no idea what it takes to make quality optics and because I am pretty slow to part with my money, I had some trouble spending that much for just an accessory.) It does make observing a LOT more comfortable and the views of the moon and Saturn I have had have been the best yet (though I have to say previous views were from indoors through a window). I thank you for your help and honest opinions when I was trying to make up my mind to get one. I have found nothing of what you told me in error. You made no claims that were exaggerated so there was not any disappointment when I got to try it. That sort of frankness and honesty is rare these days and I appreciate it! Thank you! -Jon I've had about three weeks of experience with my new Standard binos and all I have to say is WOW!!! Your binoviewers are extremely well constructed and optically beautiful. I'm using your binoviewers with a Celestron NS11 and the addition of your binoviewers has taken my joy of observing from "excellent" to "off the scale"! I do have a question, though.I'm a full convert to binoviewing and I'll be sure to strongly recommend your binoviewers! Well done, folks! -John Thank you very much Russ. I really appreciate the time you have taken for me over the past year. With all that I read on Yahoo Groups and with other astronomy communications I am thrilled that your products have received such glowing and positive remarks and evaluations. I wish you continued success with Denkmeier products.As a retired professor, I am sure you find tremendous intrinsic rewards in the way(s) with which you communicate personally with the vast variety of us human critters. The many, many positive remarks by those who have talked with you bear extremely well in this competitive business world of America today. I am very proud of knowing you and the way in which you do business. -John Huntsberger My Denk 21 Eyepieces arrived today and are absolutely a gorgeous piece of work - you should be proud of them. If how they look both in and out of their "safes" is any indication of what it is like to look through them, I'm sure they'll be terrific. (Unfortunately, it's raining now, so I haven't had a chance to look through them.)- Greg Stone Dear Russ: Sorry for my delay in writing back to you. Thank you so very much for collimating the eyepiece holders on my Denk II, and returning them so fast! That is wonderful service. Everything is great with them now, and I've been out every clear night I get enjoying the views. Thanks again! Take care, and clear skies! -Brian Schilt G'day Russ, My package arrived today. I would like to thank you for the outstanding service. I have never before experienced such superb customer service as you have provided. I will not hesitate to recommend Denkmeier Optical should the opportunity arise. Best Regards, -Mark in Australia Russ & Co. Just letting you know we continue to enjoy the Denk II with OCS. Had a time the other night where we used the system with a 2 inch Televue Barlow (for use with Panoptics) and enjoyed a spectacular view of Saturn. The combination worked surprisingly well. Using the OCS features to run between scopes has also proven a real help. I will continue to recommend your product to others. Roland Russ, and everybody at Denkmeier, Thanks. I was reluctant to ship my B/V back to you because I thought I would be without it for weeks or months. I shipped it on Tuesday. I cannot tell you how shocked I was when it was here on friday. Not only was it adjusted (eyepiece holders, prisms were fine), but it came back with machined caps. I appologize for returning for such a minor thing. Your service should be an example for all of us, I feel as though I was your only customer. Thanks again. You folks wouldn't be able to do anything about the weather? Clear Skies, -George S. Osbun Hi All, Just finished looking through a box of slides I had developed from my original tests with the StarSweeper at prime focus taken a month ago and I AM IN AWE! This thing is awsome. I shot the full Moon and there is no hint whatsoever of central darkening at 35mm camera prime focus. The pictures are as sharp or sharper than any I've ever taken. Just for grins I pointed the scope and camera at the Orion Nebula and although I'm limited to < 30 second exposures with no wedge, the results were just incredible. I highly recommend this bargain priced, excellent piece of equipment. I'll post some pictures as soon as I digitize them. WAAAHH! I want my wedge APT! Take Care, -Jose Suro Tierra Verde, Florida Well, that was another wonderful (allbeit very cold) morning with Jupiter. During the moments of better seeing, the resolution was easily sub arcsec. Here are some quick observations:The GRS is more red this year. Another fellow had mentioned this on another group and this was my first opportunity to check it out since he mentioned it. It is not salmon this year.There is a tiny dot of some sort right over the GRS. I estimate it to be about .5 arcsec or so in diameter. It was not a shadow transit as there was not one going on and it was too small. Anyone seen this? I found out something very peculiar. I put the Denk 2" OCS in 2.5x mode on the TV binovues and the TV 2x corrector on the Denks. I wanted to check this configuration before making a final determination on which to keep. Here's the peculiar part. Whichever binoviewer had the 2x corrector on it, the image of Jupiter was not as bright. I had noticed this earlier in the evening when the pieces parts were mated with their own brand. I wanted to see what happened when I swapped correctors. Sure enough, whichever binoviewer had the 2x corrector on it had a dimmer image. I checked for dew, frost, dirt, anything that might cause this. Found nothing. This doesn't seem right. I can say that the best views were with whichever binoviewer had the 2" OCS in 2.5x mode on it. Seeing was 4-5 most of the time with moments of 8-9 (.5 arcsec). I was using my new observing chair so I spent a lot of time looking at detail inside the GRS and the bands. The best view of the morning was with the TV's and the 2.5x 2" OCS, but that may have just been the seeing at that moment. Regardless, they are both extraordinary binoviewers.The seeing went to crap at about 0230, so I'm packing it in until morning for the transit of Io.So, to answer Jeff's question about a direct comparison between the TV and Denk Standards, my opinion is they are pert near equals. The 2x TV corrector is better than the 2" OCS in 1.4x mode on planets, but the 2" OCS in 2.5x mode is better than the 2x corrector on planets. Both binoviewers appear to put up very similar planetary images with the 2.5x 2" OCS. By similar, I mean similarly exquisite, with fine low contrast detail that will take your breath away.Another thing I have figured out over the past few months with the Starmaster is that a Zambuto mirror is worth every penny you pay for it.Clear skies,-Tom Hi, Russ -- I recently purchased a Denkmeier from you and it's wonderful. It is like getting a new telescope, and rekindled my interest in my 6" dob. I was easily able to mis-collimate the eyepieces to accommodate my lazy eye. Hats off, and thank you. I'm so jazzed that I'm tempted to try making a dedicated binoviewing refractor a la the TeleVue Bizarro. I was thinking of maybe converting one of the Synta 150mm F/8 scopes. But reading your Bak-4 Bak-7 discussion, I wonder if there would be any point? Hence my question: On an F/8 scope, with the ability to reach focus in either case, will the binoviewer give better images with, or without, the OCS? If the OCS view is equal or better, I might as well not go to the trouble. Thank you! -Gary Garrett Shell Beach CA Answer: No need to shorten anything. One loses the ability to ustilize our Power x Switch and our Power x Switch Star diagonal. Normal refractors are best! Keep them that way. - Russ The binoviewer arrived Monday, and I had near perfect conditions for Monday and Tuesday nights: low humidity, moonless sky, absolutely clear, no wind. The Parks Jovian 90mm works great with it (perhaps slight eyepiece collimation needed). The SCT Star*Sweeper also works great. I was able to get most of the Pleiades in one gulp, and the Orion Nebula framed with the surrounding dark dust cloud was magnificent. I used a 2" eyepiece-to-1.25" focuser adapter from Parks Optical (ScopeCity) to attach the Star*Sweeper to the built-in 90 degree diagonal or the 45 degree erect image diagonal supplied with the scope. Around 2am I remembered that Saturn is currently around Gemini's feet, swung the scope over, and there it was in 3D. Excellent product. -Michael Forte The D21s Eyepieces in their vaults and bright case arrived a few minutes ago! Wow! From the outside, they are super-fine. I'll check them out on their insides late tonight as we still are having crystal clear weather in Central Texas. Thank you very much for all your patience with me and my anxiety to get them. I will give you some kind of an subjective evaluation when I get to use them, if not tonight. &&&&(another day) We are having a freezing spell in Central Texas plus I had a date last night so I only looked and the Double Cluster and a double star in Cassiopeia (Sigman Cassiopeia). I hope to do more comparing this coming Saturday.I was using my Celestron NexStar 9.25 with a Brandon, quartz, 1/20 wave diagonal. The 21s showed sharp pin-point stars to the edge of the field. I only did a short comparison with my top of the line xxxxx 24mm eyepieces. I could not tell much difference in the central part of the field of view between the 21s and the 24s when observing the Double Cluster. At the edge, the 21s were slightly sharper. However, on Sigma Cassiopeia the division between the two stars was much sharper with the 21s than with the 24s. The stars were slightly smaller with less roughness caused by air turbulence. With this E-mail I am ordering a pair of the 14mm Denkmeier Eyepieces, Russ. When do you think they will be available? -John Huntsburger Russ: To say that I am very pleased with the performance of the new 2-inch OCS for use in my 14.5-inch f/4.4 Dob and the SR component for use in my Sky 90 is too little praise for the level of optical excellence,quality, innovation and refinement in these latest products from Denkmeier Optical. My passion for the highest quality optics and resultant images have been realized by your efforts to upgrade and enhance your offerings, by listening to the comments from your customers and providing them with useful insights and information, and by enhancing the binoviewing experience through worthwhile improvements and new thinking. The viewing of everything from deep sky objects, planetary, and solar are more than expected when I first committed to your binoviewer system last summer. Use of the binoviewer has completely changed my observing sessions and rarely is one eyepiece ever used now. It has brought a viewing "renaissance" as family and friends, who once shunned having to squint through only one eyepiece, have come back to visual astronomy. In addition to the oft mentioned "wow" of binoviewer, I and others have found that there is more emotional content and depth to viewing with both eyes, just as nature and evolution had intended. Compared to one-eyed viewing, the images have been excellent and often spectacular as familiar objects take on a new look. Although there has purported been a quantitatively measured loss of light with dim objects, more detail is generally visible using both eyes. Not only is it easier to view with both eyes, but "floaters" in the eyes are of much less concern than observing with one eyepiece, where they can become significant impediments to viewing. And then there is also that 3-D perception from use of both eyes. I've been impressed from the onset with the optical quality and capabilities of your binoviewer and 1-1/4-inch OCS system. There has never been an introduction of either optical aberrations or false color that was not already there. The new 2-inch OCS and the SR component continue that high level of performance. Views in the 14.5-inch Dob with the 2-inch OCS are just superb--high resolution, very sharp, and no color from edge-to-edge. By significantly increasing the aperture of the OCS, there is no longer the slight (but very small amount of) dimming at the edges that was experienced with the 1-1/4-inch OCS. Changing part "S" of the 2-inch OCS for the SR component has provided better parfocalization for eyepieces used in my Sky 90 refractor. Views, both terrestrial and sky, are impressive using any of my TeleVue Naglers or the Pentax 21 mm XLs. The flexibility of the OCS system, with its built-in ability to provide both low and high power that can be used with the binoviewer has provided a great range of view-field sizes and magnifications for both of my telescopes. My Coronado Solarmax 60 and BF-15 blocking filter finally came about a week ago. First images through the Denkmeier Binoviewer, fitted with the 1-1/4-inch OCS (which has now been dedicated exclusively to solar viewing for convenience) were stunning....sharp, crisp, full of detail in the beautiful deep blood-red color of hydrogen alpha. Critical comparative views, using single eyepieces (including both the regular eyepieces mentioned above and the Coronado Cemax units specifically made for solar observing and the Cemax 2x barlow) versus the Denkmeier Binoviewer resulted in images with similar detail and sharpness. And, of course, the binoviewer was much more comfortable and natural. By the way, the Cemax eyepieces, which are modified plossls (three-element vs. the usual four and with high eye relief and a 52 degree field says Coronado) have high resolution, are less critical about centering of the the solar image, and have none of the internal reflections of the eyepieces intended for night use. The downside may be their use at high powers, where the shorter focal length Naglers (7 mm and 13 mm) have a significantly larger field of view and do not appear to suffer much from the internal reflections of their longer focal length brethren. Russ, look forward to any new products that Denkmeier Optical brings out in the future. It is very rare that I recommend a product to others unless it's truly warranted. Clearly, your optics and the philosophy behind its development and continued improvements will result in many satisfied users and, hopefully, greater interest, understanding and support for astronomy. Looking forward to talking with you again soon, -B.Lee, California ,USA I cannot yet vouch for the optical characteristics--although I am sure they are terrific; however, the presentation and packaging was by far the finest quality by a mile I have ever seen. Wow !!! Congratulations! I will be up at 12,500 ft on Mauna Kea tomorrow evening, and they will be the featured item, no doubt! (I'll let you know).......(another day) ...I have only been able to get up to Mauna Kea twice since I got them, but they are just fabulous! Your eye guard is a great design, too, and make for a big comfort and visual improvement. You find the focus, then rotate them around. Super! I am a happy camper!! -Scott Church, Kona Hawaii Saturday morning was quite cold and blustery, with thick clouds lurking in the sky all day. About one half of the participants apparently heard a revised gloomy forecast and opted to pack up and go home. But towards the end of the day the sun began filtering through the clouds, and by sunset all that could be seen approaching from the west was clear, blue sky. Though the clear skies only lasted a few hours we still had ample opportunity to view many good objects. One highlight for me was viewing the globular cluster M 3 in my 25" with Russ's new "Denkmeier Two" binocular viewer fitted with matched Televue 16mm Nagler Type 5 eyepieces. Russ Lederman of Denkmeier is involved in the manufacture of this fine optical accessory. Yes, it's expensive, and yes there are still some people with understandable reservations about binocular viewers. However, I must say the view of M 3 was the finest I can recall ever seeing. The Denkmeier's merge better than any binocular viewer I have ever use, and their adjustable Optical Corrector System allows them to be used at low power with any telescope, including reflectors. -K. Blackwell, Virgina, USA I normally use my unit *without* the OCS when using my TMB. Yes, I just remove the extension. I also use a shorter 4" to 2" adapter that I bought. However, the standard adapter works for all but a few outdated eyepieces I have. I notice no on-axis degradation without the OCS. With my widest field eyepieces (24 Pans) there is just the slightest blue fringe on far-edge stars that may be coming from the eyepieces themselves. Not sure here. I have to go hunting for it on a bright white star to see it. This is not visible in normal use. There is surely nothing to complain about on-axis (or off) with mid to high power as when looking at planets. Color free. As a reference of my general sensitivity to false color (without binoviewer), I notice none ever with my TMB-152, but can readily see violet (but non objectionable) color on brighter object using my TeleVue-76 Apo. So those that can see color with a TMB-152 are more sensitive and those that can't see color with a TV-76 are less sensitive than me.I do use my OCS with my TMB-152 when I want higher power or when I want to go back and forth with my 31 Nagler in another diagonal. So I am familiar with its performance in the TMB. Again, other than the power and low power field of view, I see no difference with or without OCS. -R.D., Virginia, USA Russ: The Starsweeper had been waiting quietly next to my C-14 until the weather got better, and man what a wait. Anyhow, finally got a real good night and decided to give it a try. WOW!!! As you know, I purchased The Denkmeier Binoviewer so that I could use it in my big dob, also 6" Refractor and my 14" SCT. I was going to sell the SCT but now I have to figure a way to get all these scopes into my observatory. The StarSweeper gave me views that were so impressive I'm at a loss for words. I went out at 21:00 last night and was using 16mm Naglers and also 12mm Radians. After finding all the usual I found myself just casually slewing around the sky taking it all in. Don't really know what I looked at, I was just looking at a wondrous parade. I got the impression of sticking my head out of a porthole and into space. Lost track of time but finally came in at 3:20am this morning. Thanks for a great product in your Bino and a fantastic add on with the StarSweeper. -Norm L. Maryland, USA After using the Standard Denkmeier Binoviewer and 2 inch OCS now for a couple of months, all that I can say is that this is the best investment that I have ever made. Every one in the Louisville Astronomical Society that has looked though it has been totally impressed. You will soon be getting some order from my friends. I am using it in a 12.5 f5 dob and the views are breathtaking. But now I want more so I ordered a 15in Obsession. The views of Deep Sky Objects are amazing. M13, M3 and M5 are just 3D in the binos. The OCS makes every eyepiece better with no coma in even the cheaper ep's. I have used a pair of 21mm Pentax XLs and people who look at M42 just cry. These Standard Denkmeiers are so good that I can not see upgrading to the Denkmeier Two. PS: you better start making a bunch of them because soon my friends will be a calling! -B.Hart, Kentucky, USA Guys: I Just wanted to drop you a line regarding the starsweeper. Wow......I've finally had a chance to use this with both my 8" Lx200 and my NS11 and this is the best accessory I own, second to my Denkmeier Binoviewer. I feel like I've got two new scopes. The views are simply amazing. I've paired up 13 Naglers, 18 & 24.5 Meade swa's and the results are nothing short of spectacular. I was skeptical at first but not anymore. The wide field views that the starsweeper produce are crisp and clear on the entire field of view. The 3d effect is even more pronounced and viewing the moon is incredible. The moon used to be a nusance but now it has become a prime target. The comfort level with the bino and the starsweeper has increased my viewing sessions by three fold. I can no longer even view in mono mode and have sold all of my 2" eps. Thank you for producing such a fantastic product. Please continue to help us amateurs get the most out of this hobby/addiction. You've come up with a winner. Sincerely, -B. Crane, Kansas USA Hi Russ, I already got my Standard Denk Binoviewer back this morning! I was in shock! As Shocked as those poor Red Socks Fans.... :-) Thanks a million, and I hope to buy the Denk II's sometime next year. -Warren The following is a post I just made to the Yahoo Binoviewer Group, feel free to use it on your site if you wish. Hi All, I've had my Denks for about 4 months. I got a great deal on Astromart and have been very happy with the Denk and OCS unit. There was only one thing wrong. My TV 8-24mm click zooms are my eyepieces of choice with my Genesis SDF, LX90 or 16" NightSky Truss Dob. The problem was, my binoviewer had the friction type EP holders and changing the zoom factor with that type of EP holder was a real pain. Called Russ and explained my problem. He told me to send them in and he would switch the friction type for the self-centering locking type at no charge, even though I was not the original owner! I hated the idea of giving up Denks for any amount of time and Mars was still getting bigger at the time! So 10 weeks later I call Russ again and tell him I'm ready to part with my bino. His team got my binoviewer last Friday afternoon, 10/10/03, they had a three day weekend at the shop and I live 3,000 miles away. I got my Denks back today Friday, 10/17/03! And not only did they replace the eyepiece holder, they cleaned the prisims checked their collimation. They gave me a new low profile all aluminum face plate and re-painted the 1-1/4" nose piece! I had just hoped that they would be returned by new moon weekend, but a one day turnaround time at no charge! That is the best service I've ever had from any Astronomy vender with eight years under my belt! My hat's off to Russ and staff! - Warren Hey Russ, I just wanted to drop you a line and tell you that I got the Binos in on Monday last week, then, for some reason, the skies clouded up for about 9 days.....anyway, I had first light with them last night and I'm floored. Thank you for such a wonderful product. The craftsmanship is 1st rate. It's absolutely wonderful optically, as well. I don't think I'll ever observe with my own equipment without it, unless I have no other choice......now I gotta get a bigger scope. I knew what to expect from a binoviewer before I bought it, but I didn't know how much pride I would have for owning such a fine instrument. Thank you and keep up the good work. Hopefully I'll be able to afford a Denk2 before the Denk3 comes out.....just kidding....- Donald Scott Hi! Russ! Unbelievable, the views I'm getting of Mars through the Denk BV. I've used it in various club members scopes and my own SM. 11 and MK 67. There is big difference in favor of the Denk. I was hoping to buy an adapter that would screw on in place of the nose piece (no lenses) so I can use the Denk directly attached to a 2" diagonal (no OCS). I have a scope on order with a custom (shorter) OTA and will use these in combination, a dedicated binoscope! I saw a couple of adapters on your web site that might work, but I prefer to ask the expert, you! Thanx -Jimmy Kay Russ. I received the upgrade and used them on Saturday. All I can say is "wow" and thanks. I really think that you guys are going to be the "gold standard" for binoviewers. -Bob Noss, Astronomical Journeys Hello Russ: Just to let you know that I have just received my OCS unit. I am very impressed with the quality of the manufacture, the antireflection coatings and the anodizing of the unit. Thank you very much for such a fine product. I will be using it in my Newtonian reflector, and hope to be able to buy your binoviewer in the future. Best Regards, -Leon Montoya Japan Hey Russ... I was out of town when it arrived. Just got back late yesterday (Saturday) to find that out planned viewing session was rained out. I unpacked the box last night...WOW! You've really outdone yourself. The 'presentation' is terrific! It's the type of attention-to-detail in the case and accessories that one would expect from the very Top Tier of manufacturers. It's like the difference in build-quality between my son's Chevy Blazer and my wife's BMW! I'm not easily impressed but this got my attention. Once I've actually been able to use the viewer I'm planning to take the time to write some long posts about it. Thanks! -Mike Russ: For the record the binoviewers came in just before I left my brothers for getting ready to leave for White Mountains trip....They performed wonderfully....and it was very easy to get accustomed to the switching back and forth thru different powers. We got only two of the 4 nights for viewing due to weather conditions ...however...the one night at 11k..elevation was superb....the best ever performance of a single night in my 28years of viewing.!! My scope performed literary like a 33 to 35inch scope. NO words can describe the views we had at that elevation.. I am now a firm believer in higher elevation for remarkable improvements of viewing.. Thanks again for the very prompt service and excellent binoviewer you offer... I always promote you when I am in the field showing the fine unit to both public and astronomers at hand.... sincerely....-Dennis Young Hi Russ, Per our conversation earlier today, would you please confirm that my visa has been credited for the 1 1/4 " part S that I returned. Thanks! I love your power switch so much that I now own two; one for my NP101 and another for my 15" Obsession. As I am a visual observer and use only alt/az mounts, I used to stick with low power because I hated fumbling with eyepieces in the dark, only to lose the object from the FOV when I put in the higher power eyepieces. Your power switch has changed all that. Without even taking my eyes away from whatever celestial gem I am observing, I can go up and down in power to the magnification that best suits the object. I am surprised by how often the highest power option is what looks best; usually due to increased contrast. Aside from acquiring your Denk II binoviewer, purchasing your dual arm power switch has added more to my enjoyment of the hobby than any other purchase I have made. Thanks for coming up with such a great innovation. -Robert Fisher Thanks Guys! Fyi, I have used the PxS a few nights now...and it performs like a dream. You really make great products! I can't wait to see what you come up with next. :) -Michael Russ, I just got in after spending three fantastic hours using the new Denk II's with SCT package and the dual arm Power X Switch . This is the best astro equipment purchase I ever made since it makes my scopes much more fun to use. My old 1.3x and 2x 2" barlows work great with the Denk II SCT setup in 1x mode with my XT10 10" F5 Dob and my Meade 102ED refractor comes to focus using the 2x mode without using the barlow. The C9.25 is fantastic with the SCT setup and my 20mm Pentax XW's and 16mm Nagler T5's are all the eyepieces I need to cover all the power ranges. Having a spacewalk over the moon tonight was jaw dropping with them. Thanks for the best astro investment I ever made. Clear skies, -Joe Ogiba Thanks Russ. I used the Binoviewer for the first time Saturday night and its awesome! Fantastic views of Saturn, Jupiter, Venus, Mars, and the Moon until the clouds rolled in. I seem to have the best images from Plossl eyepieces, looking into Ortho type next. I believe the less glass in the eyepiece the better. Thanks again. Best regards and clear skies, -Greg Barker The Denk IIs w/power switch are fantastic! Hi Russ.I want to thank you for the excellent Denk IIs and the accessories! The diopters are smooth and fine-focusing and the three position power switch gives crisp views (with ample in/back focus) with all three pairs of my CEMAX EPs on all three of the Power Switch positions (mind tingling postion 1, 2 and 3)! I am one really happy camper, and will proceed to knock the socks off the crowds attending my Astronomy Day solar observing session! -Paul Hyndman Russ: The Denk II arrived at the office today, looks VERY nice! Your hot-pink 'Fragile' sticker seems to have done the trick, as the box & packaging are pristine. The bino case is bigger than i imagined it would be, but am glad there's room for my E.P. collection, which has slowly been doubling over the past 6 months in anticipation! The bino unit and the power switches are wonderfully solid, the movements are taut & precise- can't wait to get it in the scope tonite!! Will let you know how it goes... needless to say, you get double-kudos if the wife likes it, too... but if she likes it so much she wants her own, then we have a problem. Do you offer bulk discounts? Ha! Thanks, again, for working this purchase thru despite all my questions & techno-ramblings, to say nothing of our flakey Visa card. Your customer service is nearly legendary, to which I can now personally attest! High Pickerings to you, - Mike Badger Hollister, CA Dear Sirs,
Wow, was my first feeling when I got your Big Easy Binoviewer. I viewed M42 with it and it was stunning. This Binoviewer is a real winner! I also viewed the full Moon with 26mm eyepieces and it was like looking out of a porthole from a spacecraft. Grat Product!!
