NGC 4725 - A Spiral Galaxy in Coma Berenices in LRGB

This image was taken back in March 2023 when I was scrambling to get any imaging time amid unexpectedly cloudy nights here in Arizona. I had hoped to return to the target for additional exposure time once the skies clear, but just did not get around to it.

The image was taken with a ZWO ASI2600mm Pro through a Celestron 8" EdgeHD on an EQ6-R Pro mount using APT.

The image comprises:

L: 168 x 60s
R: 30 x 60s
G: 30 x 60s
B: 30 x 60s

Total integration time was four hours and 18 minutes. The image was processed in Pixinsight and tweaked in Photoshop.

This was my first attempt to image this galaxy, which was discovered by William Herschel in 1785. Hopefully, next spring will offer more clear nights so I can return to this target and capture more exposure time.

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.
