hi folks,
this is the stacked and processed images from tuesday in the light pollution and high cloud, using old flats and darks.

Looks good for such a short stack... I'm suprised the cores still over expose with the 16-bit or is this just because the way you processed. It looks very promising though - it would be great to get a whole nights worth & add some RGB as well....

Really nice to see the image you were working on the other evening, Chris, interesting to see you at work. Thanks for your help.
