Stare at the Eyes (NGC4438)

Posted on May 1, 2021May 1, 2021

www.astrobin.com/fl1soxClose up to the Markarian’s chain centred on the most estrange galaxy there, estrange in my opinion, of course.

Virgo cluster is a large cluster of galaxies due that, on this frame also appears other three NGC objects, other three IC and more than 30 galaxies from the PGC catalogue, please check the annotated version here:

It was necessary a long integration of more than 33 hours to show all this details.

On the right down side is noticeable the glow generated by the M86 galaxy that does not appear on the frame.
