my best attempt yet at M101, Pinwheel Galaxy

[red dwalf]

been a bit of a trial to process this image, some channels did not like dark frames added, some did not like dark frames or bias frames added, blue channel was a pig, but i finally got to a reasonable looking image, around 60 lum subs and around 38 RGB subs, all of 3 minutes each sub, stacked in deep sky stacker, processed each channel in Startools, then combined and tweaked in photoshop cs3.

Lovely galaxy image, but I especially like the single pink star lower right.

A swirl of space floss, very nice.

Are you using StarTools 1.6 version?

version 1.5 i believe at the moment

[happy-kat]

The beta 1.6 I find stable and there's the compose module which I can't recall if it was in 1.5.

there is a compose module in 1.5 plus but i`m having difficulty using it, i did try with the image above but i must have gone wrong somewhere as it came out monotone, had to process them individually and put them together in photoshop, plenty of time on my hands at the moment so will give it another try
