ps. M31 is actually quite nice through a 12" scope.. from a dark site, M31 can be seen with unaided eyes.

Chasing M31, fog has been my enemy the last 4 mornings.......
I have reasonably dark skies, not great, but I am about 10 or 15K out of surburbia in what they call "Park Living" The best view of Jupiter I seem to able to achieve is very similar - the lines a re sharper, but the focus seems to finish something like this?

and the bright dots of the moons around Jupiter. They are very clear and defined spots.

I thought that if collimation was an issue that I would find the stars and moon look like streaks? I can get quite some clarity of the moon, and clusters like The Butterfly cluster shine like a brooch in the sky. The images do not seem smeared at all? I admit, I fear collimation and have been hesitant to take it on, but as I said, I find my Celestron 4" to perform quite well next to the 10" Dob, untill I attempt deep sky, and the Dob is a clear winner then. Do you still think my problem might be collimation, or could I be doing something else wrong?
Many thanks to you fellows for answering this. I figured I was expecting too much to begin with? This has quietly been nagging me for a bit, I thought with a 10", 3x Barlow fitted to a 14 or 20mm EP should give me a killer focal combination for some serious close ups? The views are "nice" but not quite the close ups I seem to see everywhere? I was starting to figure a great deal of people owned CCD and liked taking long exposures? Some of the pics in here and on the net dead set look like the person was orbiting Jupiter! I felt a little silly asking thinking I was asking too much of the 'scope.....
Maybe I just need glasses..................
