I took this on a less-than-ideal night recently on another test of off-axis guiding - here's the Snake Nebula meandering through the golden starfields of Ophiuchius. Cropped a bit from the full frame as I have a bit of an issue with strong gradients on the right side of the frame, and PixInsight struggled with star matching in the lower left of the frame leading to a little trailing (maybe due to so many stars, maybe due to two 11th-12th mag asteroids in that part of the frame). I'm still looking for cleaner backgrounds, so more work to do; comments and criticisms welcomed!
15 x 5 minutes, ISO800, EOS 60D, 150mm Newtonian.
