I can conjecture that when the telescope is parked (mine at 52 degrees facing the pole star) under the influence of gravity with the unlocked mirror it settles into a normal state but slewing around moves the mirror if not locked and tilt issues become visible. This is a royal pain but I...
I agree with your comments that Celestron should have included a larger telescope-side adapter with the RASA. I was getting that vignetting even with a small-sensor ASI294MC-Pro and their 48mm option.This is a serious flaw with their product offering, and should be included in the box (...

I did try adjusting the camera closer to the telescope, .5mm and then another .5mm, but this is the best I got before calling it a night: I think I'm going to tackle tilt first tonight, but I couldn'tseeanything wrong with the stack and can't imagine the PreciseParts adapter not ...
(the mirror and corrector/lens) and set them up on some kind of open-air linear test bench. That way I can isolate the various axes of movement and experiment. My shop is only about 40 feet long though, and I don't have a second telescope to use as ...

telescope. The lens assembly has an outer diameter of 93mm. If a camera’s body is smaller than this, it will not block any light from reaching the camera sensor. If the camera body is larger than this, then it will block some of the incoming light. As long ...
would you sell the artesky? Ontario telescope does not know when they will get more. #14 bobzeq25 ISS Posts:35,918 Joined:27 Oct 2014 Posted07 October 2024 - 01:37 PM Not so minor point. One of the most maddening things about the RASA 8 is that different solutions work better for ...
