Pleiades (M45)

I had given up on this data as I could never correct the terrible gradient in the mosaic overlap using DBE. I decided to go back to this data with the new GradientCorrection tool in PI. With some fine tuning of the settings I was able to make it work and was happy with the result.

Pleiades (M45), also known as The Seven Sisters, is an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. M45 is ~444 light years away from Earth.

This 2 panel mosaic image was captured in a Queen Creek (Arizona) Bortle 7/8 backyard using a Skywatcher Esprit 150ED telescope. The telescope is mounted on a 10Micron GM2000 HPS II mount. The camera is a ZWO ASI 2600MC Pro using an Astrodon OSC UV/IR Cut filter. It was captured on 2023-01-24. The images were stacked/processed in Pixinsight.

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.
