The dwarf galaxy UGC 10822 in Draco is a satellite galaxy of the Milky Way at a distance of 280000 light years. Its matter and velocity distribution suggest it to be the object with the highest dark matter concentration known so far. It contains many red giant stars and is mainly made up of stars that are 10 billion years old. It seems to have undergone a star burst 2 billion years ago.

This is first light of my new Epsilon 160ED. I've had to return the first one because of a bad mirror. This one seems fine. In the coming weeks I'll optimize sensor spacing, tilt and collimation and will hopefully be finished in time for the summer Milky Way. I've long wanted to image this object, and the trial of the Epsilon seemed a perfect opportunity.

I've also added the full FOV with a quite a few far away galaxies visible.

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.
