M101 Pinwheel Galaxy

Revision title: +3.15hrs of Ha

Not much to say about M101, it needs no introduction. It's just so prominent in the sky right now and beautiful to look at that it was impossible to resist. This image is composed of about 10hrs of LRGB taken on two relaxing nights under a clear dark sky with roughly 5hrs of Ha added to enhance the red regions. M101 has a strong blue channel and it was very tempting and easy to boost it up and overdo it, I did my best to resist and leave it as close to the way it came together after combining the channels as possible. Happy galaxy season everyone.

Edit: Added a little over 3hrs of Ha from March 29, 2023.

Title: Star motion over time in M101 FOV

Description: I saw a beautiful animation by user Henning Schmidt demonstrating moving stars in his M51 image and though it was amazing. This is my attempt at something similar with my M101 image. The animation is a comparison of my image taken in 2023 vs one taken more than 100 years ago with the 60 inch telescope of the Mont Wilson Solar Observatory (https://archive.org/details/carnegieinstitut235carn/page/56/mode/1up?view=theater). There are several stars visible in the animation that've had significant movement in the century since both images were taken.

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.
