M109 with the Starbright C11, the Starizona F7,2 reducer (fl 2000mm)and the ASI183mm. That last one was at 0,25" per pixel way oversampling the C11's images, but not sure how this impacted the final result. I had a similar run with the Nikon D750, which did not give a satisfying result.

The C11 was guided through the 8x50 finder (no OAG)

Autofocus was a first with the Essato 2" focusser from PrimaLuceLab

With SIMBAD the faintest galaxy I could find was SDSS J115703.88+532414.6 with a listed green band magnitude of 20,893 :-) always nice to breach the 20th magnitude!

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.
