The region around the Pipe Nebula (B78), the main part of the naked-eye formation of dark nebulas called the Dark Horse. In photos it breaks up into patches of dark nebulosity, including the tiny Snake Nebula (B72) at centre in Ophiuchus. The Lagoon and Trifid Nebulas are at far left. I shot this the morning of May 4, 2014 from the Four Bar Cottages near the Arizona Sky Village near Portal, Arizona. This is a stack of 5 x 4 minute exposures with the 135mm telephoto lens at f/2.8 and filter modified Canon 5D Mark II at ISO 1600. The camera was on the iOptron SkyTracker.
The variable star Delta Cephei (at right), also a double star just barely resolved here, and the prototypical Cepheid variable star, and with it in the field at left, the star cluster and emission nebula, NGC 7380, aka the Wizard Nebula. All in Cepheus. This is a stack of 8 x 6 minute exposures with the stock Canon 6D at ISO 800, and TMB 92mm apo refractor at f/5.5 with the Hotech field flattener, with no focal reduction. Taken from New Mexico, Nov 11, 2014.
This is the rich Eta Carinae Nebula area of the southern Milky Way, with the main nebula surrounded by a variety of open star clusters: NGC 3532 the Football Cluster, IC 2602 the Southern Pleiades, NGC 3293 the Gem Cluster. This is a stack of 4 x 3 minute exposures at f/2.8 with 135mm telephoto lens and Canon MkII camera at ISO 800. Two of the frames had some haze from passing clouds, which added natural star glows. No filter used here. The field simulates the field of view of binoculars.
