M101 LRGB (old and new data mixed)

Revision title: Reprocessed 5yo data with current technologies

After some changes at my 6 inch newtonian (secondary mirror heating removed, spider adjusted, collimation, added motor focus and replaced L filter with CLS filter), I captured luminance frames of M101 again to see if my adjustments made the desired improvements. I could aquire 52 L frames at the beginning of May, which turned to be significantly sharper than the frames I captured in February and March.

Thanks to Tommy Navratil's great explanations how to combine sharp and unsharp frames (by chance he also captured M101), I could combine all the frames I made this year into this new image.

Maybe this is the maximum level of sharpness I can get out of my telescope. The only thing that not satisfies me is the color gradient in the two bright stars. I believe it is an artifact of the RGB data which I need to recapture sometime...

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.
