Description

Taking advantage of clear skies between storm fronts, I had planned to image the horsehead nebula at f3 with my SCT; however wind shear soon put paid to that, with the stars bouncing around. Fortunately, I now have my short focal length lenses, and Auriga is high in the sky. 

This image is a stack of 120s exposures taken through my L-eNhance filter and Altair 183c OSC - captured in Nebulosity with 2x2 binning and dithered using PHD2. I lost some exposures due to high cloud and wind gusts. Pre-processed with flats and darks in Nebulosity. 

Auriga has treasures for visual observers and imagers, with three lovely open clusters and complex emission nebulae which show up well in narrowband images. I’ve pushed the saturation to show these off, but otherwise standard workflow in Startools, followed by further noise reduction in Nebulosity.

There is a bit of a gradient at the top of the image but I was pleased to capture the brighter nebulosity and SH2-232
