M44 is an open star cluster in the constellation Cancer approximately 610 light-years from our sun. As one of the closest star clusters to Earth it has been recognized since Roman times. It is relatively young, like most open clusters, at 600 million years and spans about 15 light-years with about 1000 stars. Its location in the night sky at halfway between Gemini and Leo makes it a very popular object for astrophotographers in the Northern hemisphere during spring time. The large yellow red-giants make a pleasant contrast to the more abundant brighter hot blue main sequence stars. Also scattered in this image are very tiny galaxies which if you look closely can detect. One such galaxy, PGC24400, is located in the lower central portion of the image and there are at least five others scattered throughout.

I really like clusters but you would never know it since I rarely do them. In fact I have only done this once before over five years ago - this image is far superior to that image.

So I did not originally intend on doing 7.5 hours for this cluster but am glad I did. The moon was out for part of it and I was also doing other objects which were not up yet so it was very convenient.

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.
