Description

Pacman at 600mm.  f3 with 3.5 & 4 nm SHO filters.  Abour 7.5 h of exposures from Bortle 6+ suburban skies. 

There were stramge Ha streaks in the subs which I have mostly been able to process out.  I apprecieated the help from Astrobinners in the [Deep Sky] Acquisition Techniques forum and on Cloudy Nights who pointed to light from nearby 2nd Magnitude Shedar as the likely culprit.  Here is a link to the Astrobin thread, including subs and ealrly processing sowing the streaks.   https://www.astrobin.com/forum/c/astrophotography/deep-sky/pacman-ha-streaks/?page=1#post-147250
