In the constellation Virgo sits a cluster of galaxies known as Markarian’s Chain. Discovered by Armenian astrophysicist Benjamin Markarian, this string of galaxies shares a common motion through space. Centered in the image are NGC4438 and NGC4435, also known as The Eyes. They received this nickname because they look like a pair of eyes in small telescopes. Thanks for looking!

This image consists of 19 hours in HaLRGB. I annotated the image with the standard NGC catalogue, but could see galaxies in the background that were not labeled. I added the PGC catalogue, and was amazed at the result! That is a lot of galaxies in the field of view.

The image was shot using an ASI1600mm-pro camera attached to a Canon 500mm f/4 IS L II with an Astromechanics lens focuser. Mount is a Skywatcher EQ6r, guiding with a separate guide scope / camera. Additional details can be seen at https://photo-adventure.com/markarians-chain

Thanks for the kind words. With Shelter in place I haven’t been doing much outdoor photography, in it’s place I’ve had the Astro rig setup in the backyard gathering data.
