Leo 1 Dwarf Galaxy " PGC29488" and B-type star Regulus

The star Regulus , the heart of the Lion, and Leo I a dwarf galaxy are within one degree of each other. Close in the sky but Regulus is located about 75 light years away and Leo 1 is located more than 10,000 times further at about 800,000 light years away.

Regulus is the twenty-first brightest star in the night sky with an apparent magnitude of +1.35, a B type star with almost 4 solar masses. Regulus is part of a multiple star system, with a close companion star visible to the upper left.

Leo I is a dwarf spheroidal galaxy and thought to be one of the most distant of the Local Group of galaxies. The local group is dominated by our Milky Way Galaxy and M31.

There are a number of small and distant galaxies visible here as well. This is a crop from a larger image using Astrodon RGB filters (27)R + (22)G + (20)B all at 180 seconda using an 8" F/2.6 home made astrograph.

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.
