Thanks Graeme. Yeah I was having trouble getting the colour balance right in the galaxy. Doing 10 min subs increases the signal but it loses colour.
Alpal: how will stacking using kappa help? Also, call me naive, but how do I do a lumi layer given I'm imaging with a dslr?
I will do a repro as I look to have over stretched the galaxy. Too much noise in the fainter regions. I tried blurring it a bit more it wasn't working for me.
