Oh well, I have tried my best.

I have been gathering frames from the 11th of February until the 6th of May, for a total of 5585 frames and 100.2 hours integration time.

After a year I decided to process and publish this one.

--------------------------------------------------------------------------------

I started with a test 3x3 mosaic, well decided to gather most of the cluster during the season. After a lot of blood, sweat and many tears processing my first ever mosaic I realized it would be better concentrating my efforts on the center thus this image.

--------------------------------------------------------------------------------

I believe it is perfect example of why you, obviously if you can, shouldn't be shooting with a camera lens or from a city.

Strong aberrations, vignetting and gradients are present here! And I only kept 25% of acquired images...

Also a very troubled but honest background ;-)

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.
