Description

I took 6 hours each HII and OIII but when I try to combine them the result is very disappointing. Nothing I do seems to help (linearfit, background neutralization etc). I think part of the problem is that the oxygen channel is very weak and noisy. I cannot get any realistic blue or green to come through and the image just ends up looking noisier than the original HII.

If you have any advice on how to combine these channels please let me know!

The data is stacked and calibrated but otherwise unprocessed (other than application of the screen transfer function to the histogram for visualization).
