IC 698 group of galaxies

IC 698 group of Galaxies is a part of the Coma A/1367 supercluster. Its one of the smallest galaxy groups which has been observed in this cluster. The distance is about 290 mio Lj.
The members are the following listed according to RA:
IC 698    0,66 x 0,35 arcmin    14m5
IC 2850 0,44 x 0,20 arcmin      14m8
IC 2853 0,53 x 0,42 arcmin      14m6
IC 2857 0,91 x 0,16 arcmin      15m3
IC 699    0,90 x 0,35 arcmin    14m6

There is as well a "bigger Galaxy" visible at the left side which does not belong to the cluster. This is NGC 3692. The galaxy is in a distance of 125 Mio Lj and has a visual size of 1,5 x 0,44 arcmin. Compared to all the other galaxies its huge!

I was happy with the seeing on that day. It looks like that this is an Astrobin debut picture.

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.
