This binocular or finder size asterism in Hydra looks just like it sounds, like an umbrella. The Umbrella is located between Sirius, Procyon and Alphard (Alpha) Hydra.

In the center of the circle is star 6 Hydra. Once you locate this star, you can see the shape of the umbrella. The other bright star in the circle is 12 Hydra.


In the center is star 6 Hydra and the lower left is 12 Hydra. The circle is approximately 4 degrees in size which is typically a finder size.
