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.

The Pleiades star cluster, or Seven Sisters, aka Messier 45, in Taurus. The brightest part of the reflection nebula around the Pleiades at bottom is the Merope Nebula, IC 349. In this image. I’ve shot long exposures at low ISO speeds to record faint structure at low noise, to allow me to bring out the faint dusty nebulosity all around the region in processing. This is a stack of 10 x 12 minute exposures with the filter-modified Canon 5D MkII at ISO 400 through the TMB 92mm apo refractor at f/4.5 with the Borg. 0.85x field flattener/reducer. Taken from New Mexico, Nov 17, 2014.
IC 1396, a large faint nebula in Cepheus, sometimes called the Elephant Trunk Nebula, though the actual “Elephant Trunk” feature is the dark protuberance just right of centre called van den Burgh 142 (vdB 142). Also in the frame at top (north) is the red star Mu Cephei, aka the Garnet Star. This is a stack of 15 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.
