I read this post the other day and having never seen anything like your triangular stars, I decided no to guess at the problem.

however...........I went to look at jupiter the other day and your first image showing coma was what i was seeing on the slightly defocussed moons.............what the hell was going on???? I now had the same problem........jupiter would not even remotely come to focus!!!

I put in my sight tube and it was terribly out of whack.............the problem was that one of the three mirror clips had bent and the primary mirror was now shifted sideways by at least 10mm.

So having taken the mirror out and fixed the clip, i am back in business and focussing properly.

I would not have thought I could reproduce your views, but it is possible, so fingers crossed, the guys at the meeting can quite quickly line up your optics
