M44 Beehive Cluster

Messier 44 is an open cluster also known as Praesepe. It lies in the constellation of Cancer about 577 light years away, and has a core radius of 11.4 light years. Its age is estimated to be 625 to 795 million years. There is a line of faint galaxies running through this image vertically, as well. Most are 150-200+ million light years distant and receding. Just a dusty spot in this image, NC 2647 is a 15th magnitude spiral galaxy 800 million light years from our solar system, and receding at about 5.5% speed of light.

Captured RGB frames about three weeks ago while waiting for another target to get into view. I intended to get more data, including luminance, but there have been no clear nights since that weren't brutally cold/windy, and looks to be cloudy for another 2 weeks... Winter has not been kind to my astronomy hobby so far this year.

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.
