Looking good Marcus.

A bit of fuzziness on lots of the stars though. Its from overflow from the pixel wells.
Was that in the Luminance or the Ha or both?

30 minutes for Ha or 20 minutes for Lum may be too long for the 60,000 electron
wells of the 11002 chip. Length of exposure has too much noise with too short on one side versus
oversaturation with long exposures on the other side. It depends on the well depth and noise levels of the camera
and the cooling ability.

Greg.
