Some good exposure time there and the addition of the Lum has brought out lots of stars, which in this field actually looks good.
The colour version will look fantastic, ahhh I can see it already

Thanks Carl! I was pleasantly surprised at the resolution although seeing wasn't the best. It wasn't bad though.

A bit of fuzziness on lots of the stars though. Its from overflow from the pixel wells.
Was that in the Luminance or the Ha or both?
30 minutes for Ha or 20 minutes for Lum may be too long for the 60,000 electron
wells of the 11002 chip. Length of exposure has too much noise with too short on one side versus
oversaturation with long exposures on the other side. It depends on the well depth and noise levels of the camera
and the cooling ability.

Hehehe ... methinks you're too used to 17 inches of aperture. 5.9" at F11.7 requires long subs - especially on a faint object like this! Max ADU is 51,000 odd for the brightest of stars in Lum (at the bottom of the frame) and 59,000 in Ha. Yep, they're pretty well saturated but the sub length is aimed at revealing the subject so I'm happy to sacrifice a few stars for that. Really, any overly fuzzy stars you see (?) are because this is a work in progress.
Cheers mate!

Thanks Marc - still hopeful I can gather some RGB before the moon comes back!
