Revisited the Pleiades (AKA Seven Sisters, Messier 45, M45) yesterday, surprised by a rare clear night, in a month dominated by fog and gloom. This edit is much crisper than the last, which I liked, but in retrospect I probably over processed. The fine whisps of nebulosity look so delicate and yet they are light years across. Something to think about.

Located in the constellation of Taurus, it is one of the brighter night sky objects (mag. 1.6) and easily visible with the naked eye. The Pleiades holds a place in the stellar folklore of most cultures, some may recognize the constellation as the logo of the Japanese automotive brand Subaru (スバル), its namesake.

At approximately 444 light years distant, it is one of the nearest star clusters to Earth, and the nearest messier object. Easily visible with the naked eye, it has an angular size of 110 minutes, or nearly two degrees of arc.

This image is a stack of 90 sub frames, a blend of 200 and 300 second exposures taken on November 9th, 2020 using the open source #ninaastronomy software. Post-processing with #AstroPixelProcessor, and #Photoshop.

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.
