Markarian's Chain

Markarian's Chain is a beautiful string of galaxies that is part of the Virgo Cluster.  It was named after the Armenian astrophysicist, B. E. Markarian, who did extensive research on these galaxies in the early 1960s.  Member galaxies include M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435

I took full advantage of the one clear night we had last weekend and imaged this object as well as M104, the Sombrero Galaxy.  One of the most interesting members of the chain are the galaxies NGC 4435 and NGC 4438. Together they make up what is known as The Eyes.  At 52 million light years away, the two interacting galaxies resemble eyes intently staring at something or someone.

In just imaging Markarian's Chain, I have manged to capture three more Messier objects for my catalog.

Captured a Russian Satellite While Imaging Markarian's Chain.
Most people are not aware of how many satellites there are orbiting Earth. I checked Stellarium and it appears that the satellite photobombing my image was Molniya 3-41. It was originally part of a Russian military communications network but since 1967 the Molniya satellites are used for Russian TV.
