It is Astrophoto Friday again. Today we have a vintage shot from the 200-inch telescope.

This image was captured from prime focus by Rudolph Minkowski the night of October 12, 1952. The Helix Nebula is a planetary nebula. It is seen in the direction of constellation of Aquarius and is located some 450 light-years away.
