ACO 1656 in the Coma Cluster

ACO 1656 in the Coma Cluster is a great place to see how many galaxies you can capture in one image. I have counted over 3000 in this image which is incredible when you consider where it was taken from. Note: I counted by dividing the image up into 100 segments and counting galaxies I could see in 10 of those segments at random and multiplying by 10.

Most of the exposures were taken with an Astrodon NIR filter (Near Infra Red), this allows me to take quite long subs, (30min) and is a great way of going deep when imaging galaxies as you can reach those that have red shifted a bit as well. NIR tolerates light polluted skies, but I tend to not image in NIR during periods of bright Moon light.

Mixed exposures were used and are shown as the average sub length for each filter. Taken between Jan 2015 and March 2016 on 20 nights.

For those people who saw this image during a lecture I gave to the Manchester Astronomical Society in Feb this year, this is a completely re-processed image right back to calibration as I was not happy with the first result.

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.
