Same data, different processing. Does anyone like this version better than the original? They are vastly different.

Better, in part. Last one was too warm, IMO. This new version is slightly too saturated on my monitor and also too cool (blueish).

Yet another version of processing the same data. I feel like this one might be best. I was able to produce the more accurate colors of the first image with the exposure control of my second version.

What do you mean by exposures with Red, Green & Blue. Are you using filters or ?

Yes, Monochrome camera with separate exposures through different filters to create the final color images.

Great job! I think I like the first image the most as it reveals the faintest details in the galaxies.
