Description

I was surprised how well this came out considering I wasn't using any filters with a Bortle 7 sky and the moon up high at 57%.

Used HDRComposition combined with HDRMultiscaleTransform. First time using PixInsight's High Dynamic Range processes - credit to YouTube channel "Entering into Space" for a very helpful tutorial:

Gradient removal was a challenge - I guess I expected that. Dynamic Background Extraction on each of the still-linear image sets made big improvements, but I couldn't eliminate it all despite about an hour of trying.
