Atik 460EX (-10C), LRGB filters, Lumicon DS filter
Captured in APT, Processed in Nebulosity, PS CC

First chance to try out the new 460EX properly.

A “mucky” night with low transparency. Lots of star bloat but the camera has almost no noise at -10C. Processing still needs some work. Too many very red stars. Could be caused by the DS filter?
