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.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
