M101 - The Pinwheel Galaxy from Bortle 9 Sky

Revision title: M101 May 2022 reprocessed in 2023

I didn't realize how difficult it was going to be to image this faint galaxy from my inner city backyard. Did my best to process it to remove the light pollution, and noise. I might have overdone the saturation, but it was really difficult to get enough details. I get it that 5 hours is not much, but this is as good as it gets for me ... for now. Enjoy!

Description: I added 48 90s subs using the L-Pro at 120 gain. Used blink to select the best subs of all the imaging sessions. Processed it with APP, and used the Light Pollution removal tool. Finalized editing in PS for curve and levels, and used NoiseExterminator. This is the best I can do. The image shows some gradients still. But considering the integration time and the quality of the sky ... What do you think?

Description: I reprocessed the image using BlurXterminator, and NoiseXterminator. Used Curves transformation in PI to pull some color. I think it's an improvement on the original.

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.
