Great focus and a great image David.

Thanks Dean. I did take a while to achieve good focus, and was careful with darks and flats. There is noticeable coma off centre, but in general I am pleased with this camera / lens set up. I'll look at trying another stretch transform and nudging the black point too this evening. I really like globulars, and M3 specifically is fantastic.
