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.
The reflection nebula complex of Messier 78 and NGC 2071 (above) in Orion. This is a stack of 9 x 4-minute exposures with the SharpStar 100Q quad-element astrographic refractor at f/5.8 and the Canon EOS Ra camera at ISO 800. Taken late in the season on March 26, 2020 with Orion getting low in the southwest.
