M41

M41 is an open cluster located 2200 light years away in the constellation of Canis Major at a declination of -21 degrees. It is a magnitude 4.5 cluster which spans 40 arc-minutes in our apparent view. This corresponds to a diameter of 25 light years.

This open star cluster contains over 100 stars with a nicely spaced mix of hot blue stars and big red giants. It is nicknamed the Little Beehive cluster, one of a number of clusters with a Beehive nickname. I don't see much of a Beehive shape here, which is my typical experience for many of these cluster namesakes.

To my eyes, the stars of this clusters seem to form linear alignments more than the expected spherical alignment.

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.
