Caelum is an obscure constellation at the foot of Eridanus, and therefore only visible in equatorial or southern skies.

Caelum contains little of interest for binoculars; indeed there is only one star here to speak of: gamma Caeli, a telescopic binary.

Start with finding alpha Caeli. Best is to become acquainted with Eridanus. Centring Achernar in your field, move north-northeast four binocular fields. At theta Eri (review this constellation if necessary) move eastward the equivalent of 1.5 celestial hours. You'll pass Horologium's two most northerly stars, alpha and delta. Just east of these two you'll find this configuration:binoculars.

Prerequisite: Eridanus.
