M72, a Messier globular cluster (at lower right) and M73, a tiny 4-star asterism (at lower centre), in Aquarius. The Saturn Nebula, NGC 7009, is the green spot at upper left. This is a stack of 4 x 6 minute exposures with the Canon 6D at ISO 800 and TMB 92mm refractor at f/5.5 with the Hotech field flattener. Taken from New Mexico, from Silver City, Nov 11, 2014.
M75 Little Dumbbell Nebula; taken Oct 8, 2007 with 5-inch Astro-Physics apo refractor at f/6 with Canon 20Da camera at ISO 400 for stack of 2 x 15 minute exposures. Guided with Meade DSI/66mm guidescope and PHDGuide sofware. Haze and cloud prevented more exposures.
The pair of contrasting galaxies, the face-on spiral M77 and egd-on spiral NGC 1055 (above) in Cetus. Shot from home November 21, 2016 with the Explore Scientific FCD 102mm apo refractor at f/7 with a stack of 5 x 6-minute exposures at ISO 1600 with the Canon 5D MkII. Some frost at the end.
