Description

Shot over many nights when the moon was away from Cygnus and the rare clear skies coinsided. Started this on the 14th August 16 and got enough last night, 25th Sept 16, to make 4 hours a panel.

My 5th attempt at tone mapping using this old data.

My 5th attempt at tone mapping. The SHO tone map was very purple so had to reduce the blue channel a lot. I like green though :-)

C

Removed the green and applied the LargeScaleStructureEnhance script in PI. This makes a good starless image on a non linear RGB. I then added my enhanced luminance to the result. Gave my old poor data a lift.
