The Pinwheel Galaxy, M101

M101 is approximately 21 million light years from earth and is thought to contain about 1 trillion suns.

I've worked and re-worked this image many times and I think I am getting close to fulfilling the potential of the 132 subs I collected. I am still not happy with it, my acquisition and processing skills both need work. It's frustrating because San Francisco, known for its foggy summers, has had a miserable foggy spring as well, so I have been unable to get out and work on imaging.

I'm a complete beginner, only having starting doing astrophotography 8 months ago. I learn best by doing and direct experience, and of course by listening, studying and reading material by those who show mastery in a subject.

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.
