The Seven Sisters from Bortle 6

Revision title: M45 - 3rd Attempt

M45 is a star cluster, one of the closest to Earth, and is visible with the naked eye, in the constellation Taurus. It is also the closest Messier Object to Earth, with a distance of about 444 light-years. There are reflection nebulae surrounding the brightest stars in the cluster. M45 has a couple of names, the Pleiades, the Seven Sisters, and Subaru.

This is my first image this season, and is the debut for my Optolong L-eNhance filter combined with the RedCat51 in the ZWO 2" filter drawer. All processing was completed in PixInsight.

Title: 2nd Attempt - full data

Description: The next iteration of my M45. I needed less noise reduction than I thought in the linear stage, but after it was stretched, I'm not happy with the background. Still needs a LOT of work to get a smooth, dark, *non-mottled* background.

Title: M45 - 3rd Attempt

Description: Tried a couple different things here to help with the BG NR. I think it worked...I can't get the MaskedStretch in PI to work as well as I'd like, I keep getting blown out star cores on the brightest 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.
