Description

Taken on 29.01., 06.02. and 08.02.2019.

40 x 90" Ha, f/2.2
43 x 40" Optolong L-Pro, f/2.5
42 x 23" Optolong L-Pro, f/2.2
60 x 10" f/2.2

The unfiltered subs were added to regain some of the colors lost to the L-Pro LPS filter.
For the Ha subs the mount was guided in RA.
The lens should obviously be stopped down more to get cleaner edges (f/3.5 or 4 is apparently necessary).
