@gideon96 Very nice! Do you plan to make a 3x3 mosaic to capture the entire galaxy?

@wvreeven

Hey, Wouter!!
That was exactly my plan 😀

But the RC is not yet balanced (collimation in field) for this kind if project/mosaic I think, and also, it was a windy night as hell, the wind only stopped at around midnight, hence the short amount of time.

The original plan was 9 panes, around 40mins each, just for test phase, perhaps, camp for 2 nights instead of only one to gather enough data in gain 0...
Also, would like to add Ha sometime...

The (Jewish) holiday season is starting now, so maybe will catch another trip down south while the Moon is still young...

All the best!

Reprocess

I'm on a reprocess streak, due to weather, Moon, RC collimation issues and the fact I had all my project files gone sometime ago...

Masked stretch for the L/RGB, and better color balance before that.
The initial stack remained the same.
