How to find Caelum
Nearby constellations include Columba and Eridanus.
Its center is at right ascension 4h 47m, declination −39°. 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 Caelum
Caelum is highest in the evening sky, around 10 pm, in December. 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 42° N to 90° S.
Caelum 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 Caelum
Eyes
Its stars are fairly faint (the brightest, its alpha star, is mag 4.5). 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.
