M101 and lots of faint fuzzies in LHaRGB with a sprinkling of Ha

With galaxy season having really kicked off, I have started to tackle M101 from my light polluted balcony in downtown Munich, Germany. What a lovely galaxy and the size of it is just about right for my field of view.

This represents 11h of luminance, 3 to 3.5h each of R, G and B plus about 2h of Ha to add some color contrast. The stars are not quite where I want them to be yet but the many many faint fuzzies surrounding this galaxy are already starting to come out very nicely. I will be adding more luminance and RGB in the coming weeks to get the noise lower and the faint structures more visible but wanted to share the result so far. I hope you like it!

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.
