Description

A brief test of my old EOS T4i pointed at M42. Still working out how best to combine frames with different exposures into a single image, but starting to make sense. Need to play around with masking next I think.

Something "off" with the colors on my T4i and not sure if it is the camera or a natural sky gradient. Seems to go from red to green diagonally top-left to bottom-right. Gradient is there in the raw frames, so I know it's not calibration or processing. Added a CLS-CCD filter to the camera and would have thought should have resolved any major light pollution. Need to try some targets in other areas of the sky I think.
