Pleiades/M45 (wide field)

Pleiades, or the Seven Sisters, is a bright star cluster in the constellation of Taurus. It is made of seven bright stars (Alcyone, Maia, Taygeta, Celaeno, Electra, Merope and Sterope), but only six of them are visible.

This has the 45th index in the catalog created by the famous astronomer Charles Messier. Hence it is also popular as Messier 45 (M45). But this cluster was known much before that. Galileo published a sketch in 1610 that showed 36 stars that he could see with his telescope.The earliest known depiction of the Pleiades is from is about 17,000 years old: a cave drawing in the Lascaux Cave in France.

In Indian Astronomy, this cluster is known as Krittika (কৃত্তিকা). The lunar month of Kartik (কার্তিক) is derived from the Krittika and the first new moon of this lunar month is celebrated as Diwali. The seven stars are perceived as the seven wives of the seven Rishies in Ursa Major/Big Deeper constellation (Atri, Angiras, Marichi, Pulastya, Pulaha, Kratu and Vasishta) and their Indian names are Anasuya, Puloma, Arundhati, Shraddha, Havubhuh, Gati and Santati.

In Japan, this cluster is known as Subaru. The Japanese car manufacturer Subaru took its name from this cluster to represent the companies that formed together to create Fuji Heavy Industries. Their logo contains 6 stars on a blue background.

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.
