M27 the Dumbbell Nebula in Vulpecula, taken in brightening morning twilight, June 16, 2012, from home with the Astro-Physics 130mm apo refractor at f/6 with the 6x7 field flattener, for a stack of 3 x 6 minute exposures at ISO 800 with the Canon 60Da.
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.
