M45, The Pleiades

A short visit to the Pleiades and a test for better star shapes in the corners. Stars are not completely round in the corners 'of course'. The back focus is fine but you will never have completely round stars in the corners. Unless... you make a mosaic, so every corner will be in the middle of the image! So, first the middle, what you would like to have in the end and then the 4 corners, exactly in the middle. I would call it the '5 dice' method ;-) Then star align and crop to the original, starless picture. Add the stars and 'voila'! It works! Another benefit of this is that the stars in the corners have a much better color than normal! From now on, this will be my way to go whenever possible.

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.
