M92 (NGC 6341)
240s exposures in each of RGB this time instead of my usual 180s. Strong moonlight though but APP dealt with the gradients pretty well. Much deeper into the fainter stars.

M101 (NGC 4321)
Added twice as many frames as normal – still noisy. Probably need longer exposures. Bad gradients needed a lot of work in APP.
UPDATE: Used the demo versions of TOPAZ DeNoiseAI and it makes a huge difference. Removes noise without removing details. Other de-noising seems to just blur features – this is far more intelligent.
