NGC4725 in Coma Berenices

Here we have a try at galaxy NGC4725 in Coma Berenices, a spiral galaxy with a ring structure. I have heard a nick-name for this, The One-Armed Bandit becasue of the one very prominent arm. The galaxy lies approximately 40 million light years away and is the brightest galaxy in The Coma I Group. This group appears to have a couple of dozen members and is moving towards the Virgo Cluster and may eventually merge with it.

This galaxy is a barred spiral, morphological classificaion SAB(4)ab. The ring structure is an area of star formation and I tried to integrate Hα in an attempt to highlight the star forming regions. I had some success there but I did not want to over emphasize that. I was very pleased that I could do those 5-minute frames with no guiding and end up with round tight stars.

I think this is a really beautiful galaxy and I am pleased with the outcome of this one. I also like all of the little faint galaxies in the background.

I would say this is my kick-off to the galaxy season but I seem to gravitate to galaxy subjects all through the year.

I hope you enjoy this one and as always, comments and criticism are welcome. CS 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.
