This is one of my first attempts at LRGB galaxy imaging.
4x10min L and 10min each of RGB. Autoguided through a 10" with a SBig7e and Meade filters
Over-processed using MaximDL to bring out the faint outer galaxy.
Darks subtracted but no flats.

you have certainly brought out those faint outer arms! nice work!
cheers Gary

[Alchemy (Clive)]

certainly well tracked, what mount are you using and what 10 inch scope?

[theodog (Jeff)]

The 10" started as a Meade DS10. The mirrors, now marked thanks to a removalist, are all that remain. New wooden truss 'tube' and Craford style focuser.
This is carried on a Losmandy G11.
All are housed in a 'roll-of-roof' observatory.

Cheers

Lovely work, excellent resolution.

Good work there mate. Good outer structure there. I envy your dark skies there

MaximDL has a reasonably good bloom removal tool - not sure why you didn't use it. You'll need to remove the bloom on each sub before registration and combine. This can be scripted using MaximDL's scripting capabilities to simplify/automate the process. If you've got a lot of subs, its worth scripting.

The typical muted colours of an LRGB are present. Try layering the luminance at 50% opacity first, then boosting colour saturation either using saturation controls or shadow/highlight tool. Flatten the image, then relayer the luminance at 100% opacity to get full resolution. Thus the image becomes a LLRGB composite. There are many other processing tricks to manage resolution and not sacrifice colours.

Look forward to seeing more.

I think darkening the background would help a lot, but you still captured some detail in there!

Very nice image, you've captured some wonderful detail in the spiral arms.

Cheers

Nice image. Looks like you had had great focus and tracking. Well done .
