Description

Just a few subs on this before this sinks lower into the mire. This is 5 degrees lower than Abell 74.

I took 90 minutes of OIII but not too sure it enhances the RGB image any further. When I've more time I'll try subtracting the Blue and green channels from the OIII and see if that adds any improvement.

NGC 6905 looks a lot like Abell 72, to my eye, with very similar structuring. Both of these planetaries are in Delphinus.

Rev A: The OIII RGB added using the NBRGBCombination script in pixinsight.
