Constructing a mount for an old 279mm Schmidt-Cassegrain lens....
Hi all,
I'm trying to build a new mechanical structure to re-purpose an old 11" (279mm) Schmidt-Cassegrain telescope lens (just the lens ONLY, no eye-piece, no mounts) for use as a long range surveillance camera for a research project sponsored by the Navy. What I am looking for are some ideas and/or pointers for a suitable mechanical design to mount the lens (since the app is NOT for astronomy, it really doesn't matter whether the mount is equatorial or dobsonian or whatever else, I believe!) so that I can do a PTZ (Pan, Tilt and Zoom). Secondly, instead of a regular astronomical eye-piece, I intend to provide an universal sleeve or T-to-F adapter that would enable me to attach a wide variety of CCD cameras to experiment long range imaging. Once again the camera need not be optical per se! The first step right now is the mechanical piece I need to mount this huge lens for PTZ control (either manual or computer-controlled) and I'm looking for any pointers to start with. There must be amateur astronomers out there building backyard telescopes who can guide me in starting this project. Please send all your replies directly to me at . I thank you all in advance. Best Regards, Nash |

Hi Nash,
I PM'd you. Thinking an original Celestron C11 sandcast fork mount used on astromart or Teletrade. Economical, plug and play and solid. I own an original orange tube Celestron C11 setup and am extremely happy with it. --DJ (Nash Aragam) wrote in message om...
