M101 - The Great Pinwheel

Revision title: + Graxpert Denoise

Coming back to this target as the first time I tried to capture was with an Alt-Az mount.

Always visually impressive and the Ha regions really came out well even with just an OSC camera in broadband.

Bortle 7 skies limit the detail/SNR but happy with this first true shot at capturing it. Single exposures really only revealed the core, rest came when stacking and after removing the gradients.

Title: + Graxpert Denoise

Description: Used the newly released AI Denoise algorithm from Graxpert. Very impressed with the results. Allowed me to make a more aggressive stretch to bring out the details without bringing out too much background noise.

Not a noiseless image (which is good) since I captured in Bortle 7 skies over 1 night only at F/7.

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.
