M101

I had a couple clear nights to play around with my new-to-me AP900GTO and AP130GT. After spending some of the moon lit evenings dialing everything in, the clouds parted for a couple nights around the new moon, so I gave M101 a go as it was in a good location in the sky and I had not imaged it in a few years. Still amazes me how much can still come through even with all the light pollution. Minimal processing here, I will likely spend a little more time playing with the data, perhaps try and gather some Ha to go with it as well.

Description: Did a bit more processing. Aligned histogram better, a light touch of BlurX, and a bit more saturation.

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.
