This frames the region of the Milky Way in southern Canis Major and northern Puppis, rich in a variety of star clusters and some nebulosity. The field of view is 15º by 10º. At right the brightest stars are in Canis Major: yellow-white Wezen (Delta Canis Mjaoris) and blue-white Adhara (Epsilon Canis Majoris), with orange Sigma Canis Majoris between them. Above left of Wezen is the large cluster NGC 2354, and above it the smaller and brighter NGC 2362. At top left is a Messier cluster, M93, in Puppis. At far left is the bright magenta emission nebula NGC 2467. At lower left near the frame edge is the cluster NGC 2489. At bottom is the cluster NGC 2439, while the group of stars at bottom centre is the cluster Collinder 140, a distinctive object in binoculars. I call it the J Cluster as it looks like a letter J. The large diffuse faint nebulosity at top is Sharpless 2-310, though wisps of emission nebulosity extends down past the star Aludra, Eta Canis Majoris, below centre. At upper right near the orange star Omicron Canis Majoris is the faint cyan arc of the large planetary nebula Sharpless 2-308, aka the Dolphin Head Nebula, barely visible here. Left of the big Sharpless emission nebula is a small blue reflection nebula van den Burgh 98. Above the NGC 2362 cluster at the top of the frame is another small blue reflection nebula, van den Burgh 96. This is a stack of 12 x 2 minute exposures with the Canon RF135mm lens at f/2 and Canon Ra at ISO 800. The lens had an URTH 82mm Night broadband filter on it. The camera was tracked but not guided on the Astro-Physics AP400 mount. Taken from Australia in March 2024 on a night devoted to shooting 135mm telephoto lens fields along the Milky Way.
