M45 The Pleiades

The Pleiades, also known as the Seven Sisters, is an open star cluster located in the constellation of Taurus. This grouping of middle aged stars is the nearest Messier object to Earth; a mere 445 light years distant, easily visible to the naked eye and often mistaken for the Little Dipper. This one was my first attempt at LRGB imaging and processing. I'm happy with the detail however, more nebulosity could have been picked up had I had taken longer exposures. My polar alignment wasn't the best so I could only get 60 sec exposures without significant trailing. I was surprised at the "blue halo" around the image as it did not appear in the masters. I've been told the the effect is actually part of the nebula so I left it in rather than trying to remove it with the DBE tool in PI. If you drive a Subaru, look at the logo as "Subaru" is the Japanese name for this beautiful cluster.

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.
