Astroart Forum

I am new to AstroArt and I have 30 subs of the area around Sadr. These are 2x2 binned. When I preprocessed them and saved the stacked image I then postprocessed in CS5. The histogram showed the data piled up against the left wall. Obviously I did something wrong but don't know what. Should I be colorizing the subs or do that later after stacking? It would help if there was a workflow model to guide me while I learn to use this software. Help needed.

Dick,
Which camera were you using?
Did you have flats and darks to match the lights?
What settings did you use on the pre-processing screen.
More info will allow us to better assist you.

If your using a osc camera then
pre-process your subs , debayer or "colorize" then stack . If you resize or stack before debayering then
you will lose color data .
