Description

Messier 83 from central Michigan.

Processed using PI with Local Normalization, which allowed me to use subs that were partially obstructed by limbs. For the best results use the best sub for each filter and do each filter separately. This really works well at removing limb shadows as long as none of the DSO is obstructed. This also gave a very neutral background when integrated with drizzle at 2X.

Data was taken on 4/12/2021, 4/16/2021 and 4/21/2021
