thanks Ken & theo.
the tak scope gets a lot of good press. Sounds like your DeepSky RC is delivering on quality. I've been able to hold collimation & alignment well so far - plus a good 2" laser has been very useful. I also found the Catseye 2" autocollimator to be very helpful with secondary mirror adjustment. The 2 RCs I built are relatively massive and very rigid. Same goes for my Vixen VC200L CF truss rebuild - stiff with zero flexure - the original vixen steel tube had quite a bit of flex. Camera flexure was another issue I had to fix in the RC. The many connections between CCD camera, filter wheel and rotator gave some minor challenges.
Recently I've had a few different camera rigs on and off the back. I accidentally mixed up the AP 2.7" drawtubes slightly and discovered that my images had degraded noticably - I had put the mirror spacing out when I refocused with the wrong camera position (the Van Slyke secondary focusers have about 3" of travel - so they can compensate quite a bit). I have fixed the issue now. I am still using an St8me as my main camera - a large CCD chip camera is a way off yet for me. However, I am converting an EOS 5D and now have a serial cable for it plus a CCDsoft dslr driver and plan to use it to test out/tweak the image performance of the RC riding on the Paramount.
