The Pleiades (M45)

The Pleiades (M45) is an open cluster in Taurus and a jewel box of the Winter sky in the United States.

I went back to the Atik 383L+ for this image, in spite of the lower resolution, to avoid artifacts around the bright stars in the cluster. The little old CCD camera delivered once more.

I imaged the cluster with the Takahashi FSQ106EDX4 with the CR x0.73 reducer (focal length 385mm at f/3.6). The image scale is 2.9 arc-sec/pixel, which is quite undersampled even for the Northeastern USA. I drizzle integrated the color and luminance data and ultimately downsampled back to native sensor resolution.

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.
