Description

NGC 2403 taken during a full moon.

Tried out many new processing techniques especially for stretching and stars are much smaller now, but still work to do since now the big stars have some sort of halo around them.

I stretch the image manually with HistrogramTransformation and stetch the stars using MaskedStretch. Using PixelMath I combine both so the stars stay nice and small.

Also tried adding HA for this object but do not like it yet, this object has so many HA it gets to much so I might skip that for this object.
