M101-Pinwheel Galaxy

This image is a result of a collaboration with two friends, Maroun Mahfoud and Daniel Caracache. We got a total of around 30hrs of LRGB data to work with.
Processing was tough since we had some weird chromatic aberrations from one of the scopes in addition to big dust motes that weren't removed by flats for some reason.

This is our first collab work together so some problems were expected, but we liked the image overall.

Here's what my aim was while working on this image:

1- Show M101s very faint outer spiral arms.
2- Reveal the extremely faint circular structure around NGC 5485
3- Reveal the galactic cirrus around the galaxy. It's actually really faint and doesn't really show up in this image. I did go for a version where the cirrus really shows but it just got too unnatural for my taste. We probably need a lot more data to reveal the nebulosity naturally.
4- Show some details in the nearby smaller galaxies especially the E3 Dust lane in the core of NGC 5485 that shows clearly when zoomed in.

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.
