Thanks Dennis
The huge field of the Starfire and ProLine is one thing but on a galaxy it needs to be narrow field. The 1140mm FL provides just enough image scale(1.6"/pix) to reveal most of the detail in the galaxy, of course a steady sky with no wind would have produced a better result
I brightened the core region and inner arms slightly (without blowing them out) and this engulfed a couple of stars that were visible right near the core but I think the strong central glow helps to give the galaxy a bit more punch and is perhaps even slightly more realistic..?
Cheers
Mike
