Palomar 4 a small globular cluster

Palomar 4 is a small globular cluster in UMa. The size of the cluster is 2 arcmin only with brightest Stars mag 18! He is in a distance of 330.000 Lj which is farther away than the Magellanic clouds.

There are 15 such clusters on the Palomar list, all of them a challenge.

The bright and almost big Galaxy in the center of the field ist 2MFGC 8985 from the Simbad catalog. The size of the Galaxy is 30 x 9 arcsec only!!

There are plenty of other Galaxies in the background. On the right side in the middle is a group of really very distant galaxies where I could find some names in the Simbad Catalog, but no further details.

The picture is a crop from the original FF Nikon, otherwise the Galaxies and the GC would be too small! Nevertheless itsworth to go to full resolution to see all the faint fuzzies!

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.
