Description

First light with my Nitecrawler focuser installed on the Orion ED80. I couldn't get it to come to focus with the FF/FR installed so this is shot without a FF/FR. Just wanted to try it out and ended up picking this combination of NGC 6946 and 6939 somewhat impulsively.

Stacked and processed in PixInsight with some finishing touches in PhotoShop using Curves, Levels and Neal Bodoni's PS tools to increase star color, add a few spikes, enhance DSO's and reduce stars.

L 675 x 15 sec = 2.8 hrs
R 158 x 60 sec = 2.6 hrs
G 150 x 60 sec = 2.5 hrs
B 200 x 60 sec = 3.3 hrs

Total 11.27 hrs
