Although, it is best viewed in your periphery since rod performance is weakest in the center of the human eye. Captured with an unmodified Canon t2i with a 400mm Canon f5.6 L-series lens. Tracking provided by Ioptron Sky-tracker. Session completed early Nobember 2016 in Scofield, UT. 15˚F, M31 30×1. Pre-processed Photoshop CC (2017) Raw. Stacked using DSS.
