10-09-2014 Hey Russ!
Thanks again for getting the Bino to me so quick. It's an amazing piece of hardware and everybody loved it. Despite having only been used briefly it's been a topic of conversation for days. There is a call request list on the fridge now to alert the locals next time I set up. How to win friends and influence people? Buy a Denkmeier Binotron from Russ Lederman!
Couldn't be happier! Jim R. - Hilliard, Ohio

Denk 65 degree AFOV Eyepieces are optically unsurpassed. Our high index glass and super efficient anti-reflection coatings produce amazing images with boosted contrast. Yes, we match our D21 and D14 eyepieces! Each optical set is carefully measured to the tenth of a millimeter for focal length and paired together. Then we test them mechanically in the BINOTRON-27 for a final assessment. We will have stock built by mid July, ready to ship. Try them! We believe these eyepieces to be the finest optical instruments available for use in your new BINOTRON-27 Super System! READ REVIEW

NEW!! The OCS-A45
ONLY FROM DENKMEIER
"I have noted that on the Catseye Nebula, that I could not see the center star before with the D21s in the Bino before the OCS-A45 and now I can see the center star with the OCS-A45!!! That is proof positive that it has expanded what you can now see and it is definitely an improvement. Great job Russ." - Victor
With the new faster mirrors and their very steep cones, you asked us if we could make a larger front OCS Optic. Well, we have done it. Same low magnification as our lowest power OCS but a full 45mm aperture. We can't make 'em any larger!! click on "The Link" for more info. Recommended for all dobs F/5 and faster!
