Taken using Chilescope's T1 over several nights since August, but due to issues with the sessions some of the red and blue subs were rotated by more than 60° from all other sessions!

In the end I managed to get the following:
- Luminance = 8x 1200" bin1 + 2x 1800" bin2
- Red = 1x 1200" bin1 + 2x 600" bin2
- Blue = 1x 1200" bin1 + 2x600" bin2
Processing done on PixInsight 1.8.6, and final touches on DxO PhotoLab 4.
EDIT: on the final revision, StarXterminator was used to isolate the galaxies, work on that sub, then recombined with stars and BlurX and NoiseX applied, colour tweaks (although not perfect ...), etc ...

I personally really like the ring galaxy LEDA 786714 to the bottom right of the frame, which seems to have an odd very faint "cloud" object just under it before the neat double star.
It's definitely data and not processing artifact, but I cannot tell from searching online if it's due to LEDA 786714 interacting with another galaxy, something in its background, some IFN or gas in the foreground, etc ...

Description: Added red and blue subs (1x 1200" and 2x 600" for each) to the luminance.
Don't ask me how, but Chilescope's T1 rotated the field by ~60° for the 600" subs ... :-(

Description: Again playing with the Xterminator plugins, and to keep it simple I cropped the original image to only retain the "fully RGB" part at the cost of some cool galaxies ... oh well ...

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.
