M101 - The Pinwheel Galaxy

There are a few Galaxies I can get a lot of time into based on their position and this is one of them.
I've been tacking this onto the end of a lot of other projects as I can get it most of the night and I ended up with 30+ hours of exposures to work with. There isn't much to do for a short and small refractor during galaxy season, but this is one of the bigger ones, so here it is!

I've finally taken some lessons on masking and used this as a test bed for how it would go. I still feel a tad rusty on processing as the weather has been bad for awhile, but I got to try a lot of new things and can see some new ways to reprocess already.

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.
