Pleiades (M45) from Bortle 8/9 Skies.

This is the Pleiades, the seven sisters, from Bortle 8/9 skies. Also known as M45.I have about 6 or 7 hours each of LRGB. Because the main stars are so bright, and because I was using unbinned mode on the 294mm (so 12bit only) I had to go down to 30 second subs to avoid saturating the stars too badly. Probably in hindsight I should have just shot binned, but I was also imaging at 666mm FL and I wanted my pixel scale < 1”/px as I figured more resolution would be better. But the seeing was not excellent so again, probably would have been better to shoot binned @1.4"/px.

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.
