Markarian's Chain

Markarian's Chain i a line of galaxies that are members of the Virgo Cluster lying about 60 million ly. away from us. The large diffuse Messier 84 and 86 are obvious even in a small telescope.

I am really pleased with this image. The 100ED APO performs very wel and although I as usual had planned much more subs to compose a really long exporsure, the 5,5 hrs exporsure reveals the larger members members of the chain (M84, M86, NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435), but also several fainter galaxies. I also think the colors stand out nicely. The inverted color image is also very interesting, you can see it here: https://www.biophoto.net/portfolio/C00004xuSTyozN44/G0000w7tieJ_NCUM/I0000s2E8myMSi3w.

Enjoy....

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.
