NGC185 and NGC147 Andromeda Galaxy Satellites

Here we have a couple of smaller satellite galaxies of M31, NGC 147 and NGC185. I thought they make a nice visual pair in the starfield so I thought I would try to see what I could do with this in a semi widefield image.

NGC 185 is an interesting dwarf spheroidal galaxy because it appears to have a greater rate of star formation than other similar galaxies. It is also though to have a very active galactic nucleus and may in fact be a Type 2 Seyfert galaxy, which would make it the closest Seyfert galaxy to us at about 2.08 million ly.

NGC 147 is further away at about 2.5 million ly away and is larger than its partner but more diffuse. There does not appear to have been any significant star forming within the last 3b years.

(the above paraphrased from Wikipedia entries)

I hope you like this one, clear skies and good health!

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.
