Hello Folks,

As an exercise in image capture and processing I captured 35x30 sec exposures of Crux with Canon 10d and 75-300 lens @75mm FL and ISO 1600.

Stacked in K3ccd, using a dark frame from 5x30 sec exposures and a flat frame from 4 exposures in my light box. The colour from the torch bulbs in the light box was quite yellow and resulted in the Crux image going blue. Adjusted this back with Photoshop colour balance. (Hmm, probably should have adjusted the colour of the flat frame before applying it maybe).

I would appreciate it if anyone could tell me what problems you can see in this image and what I could do to improve it.

Thanks in advance,
David.
