How to find Circinus

Nearby constellations include Triangulum Australe, Apus and Centaurus.

Its center is at right ascension 14h 48m, declination −64°. Use the chart above: north is up and east is to the left, as when you face south from the Northern Hemisphere.

Best time to see Circinus

Circinus is highest in the evening sky, around 10 pm, in June. A month or two either side it is still well placed, earlier or later in the night. All of it rises above the horizon from latitudes of about 18° N to 90° S.

Circinus never rises from London: it is too far south in the sky for this latitude.

This is position and timing only: clouds, haze and light pollution aren’t included.

Seeing Circinus

Eyes

Its stars are fairly faint (the brightest, its alpha star, is mag 3.2). You’ll need a sky away from bright lights to trace the pattern.

Binoculars

Binoculars show many more stars than your eye, and bring out star clusters and brighter nebulae inside it.

Telescope

The constellation is far too large for a telescope’s view. Use one for the clusters, nebulae and galaxies inside it.

What you’re likely to see, not what a space telescope photographs. General guidance from catalog brightness and size, not a forecast for tonight.
