Description

First night using Dithering with the MGEN.

Stacking only the lights dissapointed me. Good, I did some darks and bias :-)

280mm @ f/5.6

65 subs total. Minus 5 subs with airplanes/satellites, minus 4 subs at the end of the session, because I lost the guide star which resulted immediately in star trails due to the PE of my Star Adventurer and probably inaccurate polar alignment.

All other subs were perfect :-)
