Messier 27, the Dumbbell Nebula, with a Celestron 8 HD telescope with the f/7 Reducer/Flattener for a stack of 4 x 10-minute exposures at ISO 800 with the Canon 6D MkII camera, not modified. The scope was on the Astro-Physics Mach One mount and guided with the Orion Starshoot and PHD2 guiding software. But wind still caused some trailing in RA. Russell Croman StarShrink and Gradient Xterminator filters applied, as well as two layers of High Pass sharpening to the nebula.
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.
