Description

I am struggling with processing Ha into LRGB images. There is a lot more Ha data than appears in these dust lanes. But the fun is in the learning/trying.

Total exposure time listed above does not include 60 Ha exposed at 180 sec each.

I used a different telescope with this version - AT65EDQ
