Barred spiral galaxy M109

Revision title: Increased color saturation

Another multi-night integration from my 2022 galaxy season marathon.

This Messier classic is situated very close to the magnitude 2 star Phecda (Gamma UMa), which can be seen in the full field of view.

Part of the flocking material on the inside of my telescope was hanging loose and into the light path when I did my imaging run. I was unaware of it at the time, and luckily the edge of the felt pad did not significantly degrade image quality. It did however cause additional diffraction, and that was very obvious when you look at bright stars such as Gam UMa.

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.
