Messier 27, the Dumbbell Nebula in Vulpecula, a popular deep-sky object and one of the finest examples of a planetary nebula in the sky, a nebula blown off in shells by the solar winds and eruptive events at the end of the life of a Sun-like star. This is a stack of 9 x 6-minute exposures with the Sky-Watcher Quattro 8-inch astrographic Newtonian reflector, at f/4 with the coma corrector. The camera was the filter-modified Canon 5D MkII at ISO 800. Shot from home, Oct 12-13, 2015.
M29 open cluster in Cygnus with central Cygnus nebulosity. Taken Oct 30, 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 NexGuider on William Optics 66mm guidescope. All seemed to work well.
