Thanks Louie. I am certainly happier now with the potential of the scope. f4 is so much faster than using the RC at f8. The scope seems to resolve things nicely but further tweaking will be needed.

Thanks Mike. It is a nice little galaxy isn't it? I just happened upon it whilst testing. There are not many images of it about on the web. 4 or 5 from memory.

Suavi, the collimation is easy really. You will need cats eye collimation tools, which will give you good collimation easily. Using a laser for confirmation too. The hard part is sorting the tilt. The coma corrector is very sensitive to tilt, so some trial and error is needed. You might need to do a mod to the secondary cage too but nothing is too hard; just minor tweaks really.

Welcome to speed imaging.

Greg you should have seen the tilt before I started adding shims and remember this is a crop too. A couple more shims should sort things out.
