The Pleiades

The Pleiades or the Seven Sisters (AKA Subaru) is surrounded by a reflection nebula which is blue since that is the dominant color of the hot blue stars in this region which have formed there in the last 100 million years. This constellation has been widely known to ancient civilizations and has been considered an important feature of the night sky to nearly all of them. It is featured in many interesting artifacts and art of these civilizations.

This was taken either at Lmuma Creek campground on the Yakima River or Brooks Memorial Park in Goldendale. The data was acquired in November of 2020, but I processed it in December 2022. Originally I did not publish this due to a few issues which still exist but which I have found ways to minimize to the point where at least to me they are acceptable. The main issues which stopped me from posting it originally were:

1. Microlensing on the ZWO ASI 1600mm pro seen around the largest stars
2. Halos on the lower quality ZWO filters surrounding many of the bright stars in the image

Aside from the issues I feel like this image has a lot going for it, there is sharp and interesting detail in the nebulosity around the star cluster, and overall the color is quite nice.

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.
