Stephan's Quintet - With a lot of little cousins galaxies

The project:
Initially, this was supposed to be part of a group effort... (Hi to the DSC Friends

)
But, our skies decided otherwise, so I could only get those ~31H too late in the season

So i pursued as a personal first go at full focal length (2800mm), trying to push the 28cm diameter of the setup to it's maximum long exposures solving power...

Ouch, these galaxies are quite small for this setup !
So, keeping a eye on the seeing uring imaging sessions, i switched to this target whenever i saw good moments, and at the end, i also was quite selective with the subs, keeping only a small subset of them...

The acquisitions :
In 26 Sessions from September to November 2024
I could only get those ~31H late in the season & i wished for more : more Ha and some OIII would have been nice !

The image:
I choose an LRVB + Ha assembly
I tried to show the main galaxies extensions as much as i could with the L data I got, hopefully they are present enough ?!
I also tried to keep as much little galaxies as possible, while keeping the stars in check...

I hope you'll like it
CS, Laurent

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.
