Nice shots

. M20 especially
You need to really push your exp times, though. So long as your alignment is good, try for 5 minute subs. Actually, I think your trouble is more to do with the alignment of your image train than collimation. Look at your glob pic. See how the stars are streaky...eggy in one direction. Means your camera's chip isn't exactly dead onto the light cone coming through your focuser. Either something is loose and/or you have some flexure. Or, something isn't connected properly. Check everything out to make sure what it is. Could take awhile, but once it's ironed out, things will look a lot better.
