Your focus looks slightly off in one of these. Perhaps a RoboFocus will be next on your list?
Thanks Roger!
The focus only seems out as the single M8 and M20 are crops, so the stars seem bloated. I was actually using a robofocus, I was getting an average FWHM of 3.5"arc-sec which just happened to be the imaging scale of the SBIG with the FSQ, so any smaller and I would not be able to resolve it.
The CFZ of the FSQ is 55 microns, so its been a challenge getting correct focus.
Cheers
