Description

Images taken between 15th and 25th over 8 sessions, trying out something different this time with the 183M. I wanted to try and get a good amount of the spiral arms so I went for the highest dynamic range, gain 100 and 12bit / 15min subs on all filters. Im using the Skytech LPRO filter to kill LP , then in chain the specific Baader L/R/G/B.
