M101 Pinwheel Galaxy #5

Another late night at the observatory! Decided to grab some galaxy images this time. There aren't many galaxies that are large enough for the 5-inch refractor, but this one is decently sized.

This is M101, also known as the Pinwheel Galaxy. I had a lot of noise issues processing this one, so I'm not entirely happy...I'll image it some more at some point.

M101 is a face-on spiral galaxy in the constellation Ursa Major (which includes the Big Dipper asterism), and it lies 21 million lightyears behind it. It's about the same size as our own galaxy, and hosts numerous star-forming regions (the red blotches). There are a few other galaxies in this image as well.

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.
