While waiting for some narrowband targets from home I grabbed a bunch of RGB subs on Omega over several nights. Despite the light pollution I didn't think the results were too bad.
Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: approx 60 x 300s each R, G and B
The jpeg compression doesn't do the attached image any favours. A full res version is on Astrobin: http://www.astrobin.com/107372/
I went fairly light on the processing and tried to capture some of the feel that you get through an eyepiece. Constructive criticism is appreciated, as always.
Nice resolution Rick, and plenty of blue stragglers visible
The central area is very bright which overwhelms the star colours a bit, but on the other hand it certainly provides a good impression of how packed this cluster really is!

Thanks, Rolf. That's the feeling I was going for. Just not sure if I went too far yet
Good fill-in work there Rick I like to see the centre of Omega very bright as I recon that's just how it should be...you could perhaps get a little more resolution into stars in there but the brightness would need to be preserved. Still looks good as it is though
A high impact image Rick. Usually globs I would consider APO territory but your Astrograph handled it really well. I think though there should be more blue stars in that mix. I know there are lots of golden ones as globs are usually ancient stars but often I see sprinklings of blue stars. A recent APOD implied that these globs often have stars collide and they may form blue stars.
Very nice natural approach Rick! Star colours are great, well done!
