Celestial hemisphere: Southern · Constellation: Puppis (Pup) · Contains: M 93 · NGC 2447 · PGC 136865 · PGC 136869 · PGC 78032 · PGC 78113 · PGC 78148 · PGC 78173 · PGC 78318 · PGC 78328 · PGC 78340 · PGC 78368 · PGC 78392 · PGC 78417 · PGC 78418 · PGC 78420 · PGC 78471 · PGC 78484 · PGC 78486 · PGC 86070

M93

This 6.2 magnitude open star cluster, comprised of about 80 stars, is located over 3000 light years away in the southern constellation of Puppis at a declination of -24 degrees. The cluster is about 25 arc-minutes in diameter, which corresponds to a diameter of about 25 light years.

Like most clusters, the majority of the stars are blue-white, but the cluster also contains a number of bright red giants. Some think that the cluster looks like an arrowhead, which makes some sense to me.

The cluster has a Trumpler designation of I-3-r, meaning that it is strongly concentrated with a large range of star brightness and a large number of stars.

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.
