M36 open cluster in Auriga with nearby nebulosity NGC 1931 and IC 417. Taken Nov 6, 2010 with 105mm A&M apo refractor at f/5 with Borg .85x flattener/reducer and Canon 5DMkII at ISO 800 for stack of 5 x 10 minute exposures, Median combined. Used Celestron CGEM mount and Sky-Watcher SynGuider on William Optics 66mm guidescope. All seemed to work well.
The Auriga trio of Messier clusters at top: M37, M36 and M38 (L to R), with associated nebulosity, IC 405, the Flaming Star Nebula, and IC 410. Taken from New Mexico, with 135mm telephoto at f/2.8 and stack of 5 x 6 minute exposures with Canon 5D MkII at ISO 1250, on iOptron SkyTracker.
A collection of bright star clusters and colourful nebulas in central Auriga. Messier 36, aka the Pinwheel Cluster, is at far left. Messier 38, aka the Starfish Cluster, is at top left, with the small cluster NGC 1907 below it. The large nebula at right is IC 405, the Flaming Star Nebula surrounding and extending from the star AE Aurigae. The part of the nebula around the star is blue reflection nebulosity. The large nebula at bottom is IC 410 surrounding a loose star cluster NGC 1893. The small nebula left of centre is IC 417. The smaller nebula between IC 417 and Messier 36 is NGC 1931. The colourful group of stars between IC 405 and 410 at right is the Little Fish asterism. This is a stack of 8 x 8-minute exposures through the Borg 77mm f/4 astrograph and with the Canon EOS Ra red-sensitive mirrorless camera, at ISO 800. Stacked, aligned and processed in Adobe Camera Raw and Photoshop 2020. No nebula or light pollution reduction filter was employed in taking the images. I shot this from home November 25, 2019 on a very fine if frosty autumn night. The Dew Destroyer heater coil from David Lane wrapped around the front objective nicely kept off the frost. As the temperature was -10° C, I did not employ Long Exposure Noise Reduction or take and apply dark frames.
