Markarian Chain and Virgo Super Cluster (Dark Version)

Galaxies as far as the eye can see...


From Wikipedia: Markarian's Chain is a stretch of galaxies that forms part of the Virgo Cluster. It is called a chain because, when viewed from Earth, the galaxies lie along a smoothly curved line. It was named after the Armenian astrophysicist, B. E. Markarian, who discovered their common motion in the early 1960s[1]. Member galaxies include M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435. It's located at RA 12h 27m and Dec +13° 10′.

At least seven galaxies in the chain appear to move coherently, although others appear to be superposed by chance


I managed to escape last weekend from the recent incessant rain in Seattle and head out to Eastern Washington, specifically Yakima.

This is my second ever attempt using a 5d mark II camera for astrophotography.


About 3 hours of data, each sub about 10mins each. I would have gone much longer had clouds not come in and ruined the latter part of the night.

Some galactic cirrus (IFN) can also be seen in the original image. I will perhaps post a version when I figure out how to remove all the noise.


10min subs: 19 total. Several others were ruined by high clouds.

Location: Lmuma campground, Yakima Canyon

Camera: unmodded 5d mark II
