DENKMEIER OPTICAL, INC. PRESENTS:
THE MULTI-PURPOSE 2” OCS™ Patent Pending
See our website for diagram of 2"OCS and instructions and see the "Testimonials" page ON OUR WEBSITE for some 2" OCS comments.
At its shortest length, it is 3.5” long. This is a “TRUE”
2” format accessory. The custom optics are FMC with ratings of 99.7% transmission per air-to-glass optical surface. This has been specifically designed to handle steep light cones of fast dobsonians and reaching focus at 1.35X or less is guaranteed!Threaded for 48mm filters too! Works in refractors with 2" focusers too!
The 2” OCS™ comes with a hollow 2” nosepiece in Addition to the configuration shown in the photo. The Hollow 2” nosepiece replaces Part “O” so that the System also works at a beautiful 2.5X for planet and Lunar observing and is threaded for 48mm filters. $299 (With Deepsky Binoviewer)
Also available for the Tele Vue Bino Vue.
With a special additional adapter that replaces the nosepiece, the
2" OCS will sit fully flush! -$368 (includes adapter)
The 2" OCS is a definite winner! I'll give it a REAL workout in the coming nights but, it's immediately apparent that I'm FINALLY getting full-aperture binoviewing in my 24" f/4.2. I'm pulling out threshold stars at least 1/2 mag. fainter (probably greater, but it will take more critical testing to determine the exact difference) with the Denkmeier than with the "xxxxxx". And with nearly double the true fov!
