This is a two-panel mosaic of nebulas and clusters in southern Gemini and northern Orion. The Messier 35 star cluster is at top accompanied by the smaller cluster NGC 2158. At left near the orange star Eta Geminorum is the crescent-shaped Jellyfish Nebula, IC 443, a supernova remnant. The fainter, diffuse nebula at far left is IC 444. At bottom and over the border in Orion is the Monkeyhead Nebula, NGC 2174. The little round nebula above NGC 2174 is Sharpless 2-247. This is a mosaic of two segments for the northern and southern halves of the scene, with each half being a stack of 6 x 8-minute exposures at ISO 800 with no filter, plus a stack layered in of 6 x 8-minute exposures at ISO 3200 with an Optolong L-Enhance filter to bring out the faint red nebulosity. So this is a stack and blend of a total of 24 exposures. Alll were with the Canon EOS Ra camera on the SharpStar HNT150 Hyperbolic Newtonian astrograph at f/2.8.
Grus Quartet of galaxies in Grus the crane. They are from left to right, east to west, NGC 7599, NGC 7590, NGC 7582 (largest and brightest) and NGC 7552 (farthest away from main trio). This is a stack of 5 x 12 minute exposures at ISO 800 with Canon 5D MkII and Astro-Physics 105mm Traveler apo refracrtor at f/5.8. Taken from Timor Cottage, Coonabarabran, NSW. Australia, December 11, 2012.
The extensive Gum Nebula area in Vela, an interstellar bubble blown by winds from hot stars, with the False Cross at left. This is a stack of 4 x 5 minute exposures at f/3.2 with the Sigma 50mm lens and filter-modified Canon 5D MkII at ISO 800. Taken from Coonabarabran, Australia, December 2012. High cloud added natural glows around stars. Star clusters NGC 2516 (below False Cross) and IC 2391 (right of false Cross) stand out. Superhot star Gamma Velorum is at centre.
