Sextans A

This small faint dwarf galaxy is located only 4 million light years away in the constellation of Sextans (naturally) at a declination of -5 degrees. It is a magnitude 11.9 galaxy which spans 4 arc-minutes in our apparent view. This corresponds to a diameter of just 5000 light years.

The main parts of the galaxy are faint, as most dwarfs are, and I am not able to resolve the individual stars. Several star clouds and HII regions make it more interesting. Adding Ha would make it more interesting and I may do that some day. This galaxy looks similar to Arp 268. My collection of dwarf galaxies is seen here.

My friend Scott (@wsg) has a wonderful image of this object taken with a large Planewave from Chile here.

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.
