m51 - stacking of 2020 and 2022 images wth different setup

This image is the sum of this one taken during 2022

and this other taken during 2020

I have found out that Astroart 8 is able to combine images with different size. Once stacked processing has been as follow with Astroart:

Gradient removal with points - deconvultion - stars compression - DDP

In PS level adjustment.

I have tried several softwares to do image taken with different setup combination. First one was registar, than I know that APP and Pixinsight can do. However I am used to work with Astroart, and result this time surprised me. It's time to test this feature with all the M51 images taken during almost 20 years of Astrphotography and see result.

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.
