M104, Sombrero Galaxy

Revision title: 2x Drizzle Version

Slightly bigger than our own Milky Way, the Sombrero Galaxy (M104, NGC 4594) is a giant elliptical galaxy that stretches nearly 100,000 light-years across that sits at the border of the constellations Virgo and Corvus, approximately 31 million light-years (9.5megaparsecs) from Earth. From SW Ohio and 39 degrees latitude, Dec -11.3 finds M104 quite low in the southern sky, and in our yard, barely clears the tree line. It's apparent size of 9x4' also makes it a small target for the Esprit 100, though the wide angle view in Version A shows just how isolated the galaxy is from other prominent DSOs. Located south of the Virgo supercluster, it had been thought to be part of the Virgo II Groups, although more recent studies suggest it may exist in isolation or only including its extremely small (and not seen in this image) companion galaxy UGCA 287 (PGC 41743); UGCA is from the Uppsala General Catalogue Addendum that includes small northern galaxies first published in 1973.

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.
