Doesn't look much at first sight - no spectacular Messier objects to find anywhere!

I could verify with SIMBAD and ALADIN the limiting magnitude in this image which is betond 20. One little galaxy had a SIMBAD g value of 20,059.

More on my website: www.drogenberg.be

Please look at the larger image to find pile of dozens of little galaxies. A lot of the 'fuzzy stars' turn out to be galaxies!

Abell 2199 is a cluster of galaxies - situated to the upper right of the Hercules keystone.

The brightest member is NGC6166 (with 4 components A,B,C & D), magnitude 11, all others are down to magn. 16 - 17 range and beyond. Distance 50 million LY. Abell 2199 is a prime example of the missing mass enigma. In total there should be thousands of galaxies...

How many galaxies can you count? You need to zoom in! I found almost 200 in this image, not counting any 'suspicious' stars.

Tracking was not always excellent during all sessions (I had now 6 consecutive nights of imaging from home, something only outdone by France holidays imaging, 4 last nights were used for this object).

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.
