Hi Paul,
Thanks for the feedback, just realised I only put the small vsn on the Eta image in the link...full res is here if you would not mind having a look:

Obviously softend a bit by the jpeg fromat but it should suffice to see if the scope is perfoming "normally". I did not use flats.
Thanks for looking!
John

Field curvature is normal for RC telescopes and like you said it will be less evident with the smaller sensor. I can be sorted with flatteners and reducers too.
The eta image looks sharp the detail looks as it should. You can compare your images to my eta image with the RC8 and a 40D if you like.
I look forward to more images coming from you.
