Description

NGC 6888 Ha only.

Data came out very clean and did close to nothing for processing, only a stretch... OIII and SII will be added soon. The Astrodon 3nm filter is looking very good, absolutely no gradient while most data has been collected under grey nights!

Used darks to remove the ampglow.
