Description

Fujifilm X-T10, Samyang 135mm f/2.0 @ f2.0, ISO 1600, 40 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing in GIMP, taken July 31 under Bortle 3/4 skies.

Sky conditions seemed about perfect and Sadr was nearly directly overhead, making processing simple. Taken on my third consecutive night of astrophotography - I'm not going out tonight despite the likely clear skies - I need a break.
