M 83 - new try .. must new try

New try, but with full Moon. The exposure was limited to 60 sec because of background glow.

The process had attention to recover some red information to areas were the stars are born.

GSO 305 mm - Canon T 3 - ISO 800 - 56 x 60 seg (60 min) - OAG - Coma Corrector - Skyglow filter.

note: the second photo is over-processed to identify some dust position. But what I found as important is a parallel and horizontal black line. I saw some time ago a post here about this matter. But I don't remember exactly who post and what was told. I need seach for it.

Any idea about it ?
