Revision title: Rev A

This photograph of "The Seven Sisters" is really humbling to me, as when I compare it to my first image I took of it several years ago, the difference in quality and detail is truly night and day. I believe I have always had a challenge imaging this wonder of the night sky because it is a broadband light spectra object, therefore, easily washed out by artificial light pollution sources. In this photograph, given the generous amount of signal integration time I have collected, you can just only begin to see some of the fainter grey dust around the primary stars.

To be honest, despite photographing this group of stars multiple times over the last few years, i still have no clue which stars exactly make up the seven.

Title: Rev A

Description: Added 6 more hours of integration. Improved colors to be more natural violet blue and not greenish blue. Blurred stars slightly so that their cores are not as intense. Blended 30% of older revision onto newer 25h version to create a composite I was satisfied with.

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.
