The Messier star cluster M38 at left, with the smaller NGC 1907 cluster below, amid a complex field of nebulosity in central Auriga, including from left to right: IC 417 (at bottom), IC 410 (lower right), and IC 405 (at upper right), aka the Flaming Star Nebula. This is a stack of 6 x 6 minute exposures at ISO 800 with the filter-modified Canon 5D MkII, and through the 92mm TMB apo refractor with the Borg 0.85x flattener/reducer for f/4.5. Mounted on the Sky-Watcher EQ6-R mount for testing. Taken on a -10° night on January 4, 2018 from home. Guided with the Starshoot auto-guider run by PHD2 on the Macbook. Diffraction spikes added with Noel Carboni’s Astronomy Tools actions.
