Messier 45

Messier 45, Pleiades.

This was a very challenging target logistically. Last year I shot M45 and was just very unimpressed with the framing due to my focal length. So this time I decided to do a 4 panel mosaic. It was a challenging learning experience.

My coma still remains an issue, an it lead to some interesting artifacts after the mosaic merge. Some of my stars are very strangely shaped. I also generated a strange color gradient after the panels were merged. I'll have to take a deeper look at learning how to color match the colors better.

Advice and critique very much welcome!

Either way, I am MUCH more happy with the framing of this image.

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.
