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 Heart Nebula (at right, aka IC 1805) and the Soul Nebula (at left, aka IC 1848, ad also the Foetus Nebula), in Cassiopeia. Just right of upper centre is the open star cluster NGC 1027. The star cluster in the middle of the Heart Nebula is called Melotte 15. The patch of nebulosity at upper right detached from the rest is NGC 896. The field is filled with numerous other clusters and dark nebulas from lesser known catalogs. The field lies right on the Galactic Equator, with most objects here located in the Perseus spiral arm, the next one out from ours, some 6000 to 7500 light years away. This is a 3-segment mosaic, taken Nov 15 and 16, 2014 from New Mexico. Each segment is a stack of 12 x 6 minute exposures with the filter-modified Canon 5D MkII camera at ISO 800, through the TMB 92mm apo refractor at f/4.4 using the Borg 0.85x field flattener/reducer.
