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.
