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.
Cocoon Nebula area with M39 and NGC 7209, taken August 15, 2007 from home. Stack of 3 x 4 minute exposures at ISO800 with Canon 20Da and 135mm L-lens at f/2.8. Field equals 7° bino field. Contains dark nebula B168, Cocoon Nebula IC 5146, M39 (right) and NGC 7209 (left) open clusters. Slightly soft focus.
M39 with 101mm Borg apo refractor at f/4.1 and Canon 20Da camera at ISO800 for stack of 4 x 5 minute exposures. Taken on a very warm night in July 2007. Taken with HEQ5 mount autoguided with ST402.
