A mighty fine image Marcus, lots of depth and detail.
I agree the stars look a little silver and monochrome - almost seperated from the background at the original size, so I openned the original size and then viewed it at 60% and it looks really great.
I would assume you have picked up the reflection nebula because you did a lot of Lum, had you done just a HaRGB you would have missed it I'd imagine?
Good to see imagers posting full res images too....we are a rare breed
Top stuff, you have a great FL/FOV to work with
