Capricornus,
Uranus and Neptune
|
The Capricornus costellation is not very
pretty, and there is (in my opinion) only one interesting object visible
at the binocular: alpha cap in fact is a pretty double, with the stars
6' apart. With a good sight it's possible to see it at naked eye.
But in this image there two "guest stars":
Uranus and Neptune. They are indicated by an arrow, Uranus more bright
at left and Neptune at right.
