Plus, scope doesn't arrive for another week or so.

Looked back over my old data on NGC 2070, PI was telling me that I was getting ~ 1.75'/pix so I thought my might try drizzling and see how that went. The image itself is 12x400s RGB taken from my light polluted back yard so it's not overly deep and still pretty noisy.

Some of the brighter stars have a bulls eye, this is caused by the HDRTransformation, still trying to figure out how to eliminate it without causing a bunch of other issues. Masking the bright stars helps a bit.

I think I also took the red subs a bit too close to the horizon (compared to the G&B), brighter stars have red halos.

Criticisms most welcome
Great image Colin, I can offer some advice for dealing with the star core issues. It will most likely be the brighter stars that suffer from this so try to mask them before applying HDR. Star mask would be suitable, or a range mask - you should only need to target the larger / brighter stars. Perhaps a bit of trial and error.
