Hello Friends,

this image was shot along with my other image of NGC 3718 during 5 nights. The conditions were also quite mixed. In order to get a decent image it required a lot of data. Shooting unguided helped here a lot not introducing errors due to seeing impacted guiding.

I have compared my result to some other images on AB, but my result differs in some ways, which made me scratch my head. Not sure why it is different, but it is... Well...magic.

I have not cropped the image, since there are so many small and faint galaxies in the background. This is like searching for Easter Eggs.

May I also draw your attention to the small galaxy very down: NGC4712. This is like a small gem even revealing some details. It has an approx. diameter of 135.000 light years and is 60Mpc away, whereas the big brother is 170.000 light years wide and approx. 54 Mpc away. NGC 4725 has an active nucleus, indicating an active super massive black hole.

Also a nice tiny gem is the galaxy PGC086434 on the right lower side.

Actually there are many tiny surprises. I have stopped counting

Please enjoy!

Title: Annotated raw L stack using PGC

Description: As requested from the comments, I have uploaded an annotated version of the RAW LUM stack (no processing at all - just solved and annotated in PI).
Unfortunately PGC does not contain all galaxies visible the image. There are many more than indicated.

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.
