M45 - Pleiades / Seven Sisters / Subaru

The Pleiades is one of the most well-known of all Open Clusters of Stars, with between 6 and 14 members visible to the naked eye depending on viewing conditions (and over 1000 Astronomically identified members). This Cluster has been known as a group since the days of antiquity, being referenced in the Old Testament and Quran as well as the Greek texts of the Iliad and Odyssey. It features in mythologies across the world, from Persian and Arabian to Nordic and Polynesian and several Amerindian Cultures. In Japan, it is "Subaru" and also the pattern emblazoned as the Car Company's Logo.

The bright blue Nebulosity is not part of the Pleiades, but is actually a large Interstellar Dust Cloud between Earth and the Open Cluster being back-lit to show the whorls and whisps and shockwaves that we name the Maia and Merope Nebulas (the two prominent Pleiades lighting much of the Nebulosity).

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.
