Image stats:
RGB 38 x 5m each.
Ha 50 x 5m
Lum 30 x 5m
Total integration 16 hrs.
The Ha component contributed very little (a tiny red smudge), so hardly worth the effort.
Even the Lum improved things only slightly.
I did try 30s subs to find an improvement in the cluster, it did work...but then how to combine it all?
All good fun and thanks for looking and hints always most welcome
