I have a new probem with the RC, on the bench the collimation is perfect, however, on the mount its out significantly. It was collimated visually on the bench, checked with a star test visually, and looked close, however, when the camera star test is done it was way out. I adjusted the secondary only to make the camera star test perfect and did some test shots - and things looked good. Now back on the bench this morning it's way out again when checked visually. So what is the problem? Is it flex due to the DSLR ( used just my plain uncooled Canon, so not as heavy as the cooled camera).
The scope has the focuser collimation ring and that was used to centre the laser with full imaging ring/focuser setup during bench collimation.
I'm at a loss to know what the issues is now - any ideas?
