Delivery Update: 05-15-2013
We are currently producing prisms, eyepiece lenses, mechanics and expect to be assembling during late May. We believe in quality first. As we assemble and implement 100% quality control procedures, we must take the time necessary to inspect and test at every phase. We do apologize for not being able to deliver within the week. Orders placed in January and February and March and April should all ship in Late May, early June. We expect to build stock that is ready for immediate shipping by July.
Note: We do not charge customers until we ship though in a few cases, we are requested to charge early. In other words, we must ship to experience income! That notwithstanding, we cannot rush any process and the best thing for the customer and our commpany as well, is an adherence to the strictest quality procedures. This is our mantra and we will stay the course. You, the loyal customer will benefit in the longrun, knowing that your BINOTRON-27 was worked on individually with the greatest care possible!
Thanks to all of our old, and new friends who visited our booth at NEAF, 2013! We did not have any BINOTRON-27 Super Systems to sell at the show because we do have customers patiently waiting for delivery who had ordered earlier. We will put 100% care into building each system as we are preparing them for shipment in the coming months. They will be worth the wait, we promise. Thanks so much for your support!

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!
