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. The bright star is Delta Ceti. Russell Croman’s Gradient Xterminator applied to even out the background.
The Horsehead Nebula (B33) at bottom, below the star Zeta Orionis (aka Alnitak, the left star of Orion’s Belt), plus NGC 2024, the Flame Nebula, above Zeta. The field includes Messier 78 at upper left, a reflection nebula crossed by lanes of dark nebulosity, plus the smaller NGC 2071 above the main M78 nebula. This is a stack of 12 x 6 minute exposures with the filter-modified Canon 5D MkII at ISO 800 through the TMB 92mm apo refractor at f/4.4 with the Borg. 0.85x field flattener/reducer. Taken from New Mexico, Nov 17, 2014.
