Description

Through several nights I collected almost 30 hours of narrowband data. To avoid star staturation in the cluster I used 5-minute subs, which then made me struggle when dealing with background noise (used a CCD with pretty high RN). Also, had a hard time calibrating the frames.

Description: Used a different workflow, dealing with the noise from the start. I like the result much better, particularly the star profiles, although I lost the transparency of the dark lane, which I liked.

C

Description: Final revision, recovering part of the transparencies in the dark structures that I liked.
