Revision title: M101 Wide-Field reprocess

This was my first time out with my new (used) modified D5100 - unfortunately due to weather and illness I wasn't able to catch the end of the winter nebulae and I'm too impatient to wait for the core season to start! One advantage this gives me is the intervalometer option that I don't have with my D3500, so I was finally able to set up the camera in the yard and go to bed, and collect everything in the morning (glad it enables data collection during the work week!) I learnt a few things, notably I need to investigate some alternate power sources as my batteries gave up after just under four hours work of 30 second exposures. Still managed to get 7hr44mins of data over two nights so I'm pleased I had plenty to work with. At least this was a good opportunity to get familiar and comfortable with my new gear before the summer nebulae appear. Next stop at next new moon will be Rho Ophiuchi!

Imaged on April 5th and 6th, 2022
Nikon 180mm f2.8 lens effectively stopped down to f4 through use of 58mm Haida light pollution filter

Description: Never felt entirely happy with the original, I overdid the noise reduction. Had another go and like this one better in terms of the texture and color balance in the spiral arms.

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.
