M101 Revisited with the Esprit 120. This time I only gathered Quadband data since I was gathering images after M106 dropped below a suitable altitude.

The Esprit with the 2600MC Duo file like a good match for my conditions and this sized target. Combined with actual CC and better stretching via Siril GHS, there are much more details here compared to my small refractor's version.

I'll definitely revisit again once I grab Pixinsight soon™ and Ha data to emphasize the nodules. I also need to figure out how to remove all this noise that's in all of my images. I can't tell if it's processing or the stacking in ASTAP or some other process. I might need to grab the trials for NXT, BXT, Pixinsight to make that comparison.

Processing:

ASTAP Stack, Flats, darks, flat darks
GraXpert crop and background extraction
Siril

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.
