Description

16 Lights 5 Minutes each @ 1600 ISO. No Darks!

Auto-Guided with PHD, while APT took the pictures, dithering between the frames.

DSS Stacking with Sigma Kappa Clipping and - very important - background calibration PER CHANNEL.

Otherwise I was getting reddish "noise" in the background.
