Thanks Erik!

Star shapes also look a little out of round too, so guiding might not have been optimal and hence the blurring.

It might all be a once of thing, but I would have expected sharper detail from this scope. Just my opinion only.
Thanks for looking Paul and appreciate the feedback!

No, nothing wrong with the galaxies that I can see (given only 4.5 hours of data) but the seeing was mediocre for the second 2.5 hour session (2.6 arcsec FWHM (at the limit of acceptability) as opposed to 2.1 for the first session) but I used the data anyway. As Mike said, beggars can't be choosers! I guess this is my lot for living where I do.

And yes, you are correct, I did have some minor guiding issues in the second session. Alas, shooting at 0.59 arcsec/pixel and posting at full res leaves me no place to hide! I'm not going to quibble with the current state of play though.

All up I'm very excited about how the scope will perform under good conditions (I've seen what it can do when seeing is 1.8 arcsec FWHM). I'm less excited about the frequency of such sky conditions though! That's why I'm in the early stages of planning for a move

Perhaps you should compare this with some other full res images on the web at the same image scale (and not taken from the top of a mountain)?
