Various emission nebulas in southern Gemini and into northern Orion. At top is the bright star cluster Messier 35, with the small more distant open star cluster NGC 2158 below and to the right of it. Left of centre is the shell-like supernova remnant, IC 443, or the Jellyfish nebula. The small blue reflection nebula above and to the left of it is IC 444 amid a field of fainter emission nebulosity. The round and bright nebula at bottom is IC 2174 in Orion, or the Monkeyhead nebula. It is mostly an emission nebula but has some blue reflection components. The smaller round red nebula above it is Sharpless 2-247. It appears to be an ionized HII region, as a form of bubble, but is not a planetary nebula. The orange star to the right of the Jellyfish is Propus, or eta Geminorum.
