Description

Data acquired over multiple days during the month of January 2017.

1x1 binning on lum, 900s and 600s subs

2x2 binning on Ha, R, G, B, 600s subs

I think I've over saturated the Ha a lot, and probably shouldn't have blurred my color via noise reduction so far. But over all quite happy with it. My second "big" project in terms of integration time. The first one being a 2 panel mosaic of the elephant trunk nebula.
