Eta Carinae - the best I can do right now I think

After tonights effort I've hit a wall with this thing. I'll get back to it later with some more data and after I've learned a little more about ImagesPlus. I also need to research the colours involved a little more. Sorry about the field flatness - I have a fix for that coming. I'll have the ST-8 to fool with soon so there's an avenue to get to image fainter objects and move on from Eta et al.

This image is made up from 8 x 15min (900 sec) subs @ISO800 plus 4 x 3 min (180 sec) - a total of 2.2 hours. Merged into a Smart Object in CS3 after manual realignment of layered frames. I then subtracted one 15 minute dark frame. I have to say that the standard 350D behaved beautifully - and even after 15 minutes there was minimal amp glow and nearly no noise. I've included that dark frame.

After that I pulled it into ImagesPlus and mucked around a bit with colour balance. Finally I brought it back into CS3 to adjust the curves a little.

Worked out OK I think.

EDIT: Added cropped (1024x768) version
