How to find it

- Eta Piscium
What to look for
- The Circlet of Pisces, a small ring of faint stars that stands out on a dark night.
Binocular and telescope targets
- M74: a faint face-on spiral galaxy, a challenge for small telescopes
Using it to find other things
- Pisces is the constellation that holds the Sun at the March equinox, as the Sun crosses the celestial equator.
About this constellation
Pisces is faint and spread out, so it demands a dark sky. The Circlet is the easiest part to find, and the two long lines of stars give the rest of the shape.
The Sun currently crosses the celestial equator, marking the start of spring in the Northern Hemisphere, while it is in Pisces. That spot is known as the vernal equinox.

Visibility depends on your latitude, the date, and the time of night. The months above assume a typical evening from the contiguous United States, so use a planetarium app to confirm what is up tonight. Never look at the Sun through binoculars or a telescope without a proper solar filter.
