As this galaxy was unknown to me, I tried a lucky shot - and there it is! Leo I was the only dwarf galaxy I was aware of in the Leo constellation. On the Grandpre observation weekend, one of the observing challenges was Leo II. So I got a quick snapshot of it (only 90 minutes) to have an idea. It turns out well in the picture, clearly visible as a galaxy but also some of the brightest stars (around mag 20) of the galaxy itself are visible.

One tiny, edge-on galaxy peers through Leo II (left inside of Leo II). This is (ref:Skysafari catalogues) PGC5250798, a magnitude +21 galaxy - distant at an incredible 6 billion lightyears, and even more incredible, receeding at an asthonishing speed of 109817 km per second. That is 36% of light speed.

Leo II itself is magnitude 11th, with dimensions 14.8′ x12.2′. It’s only 457 thousand light years away (four times the diameter of our own galaxy). It is also really small with a diameter of 1961 lightyears.

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.
