α Crateris


It's easiest to find alpha Crateris by coming from Hydra.

From nu Hydrae you'll see to the southeast alpha Crateris: binoculars.

At 4.1 visual magnitude alpha Crateris isn't the brightest star of Crater. That title goes to delta Crt which is slightly brighter (3.6) and even gamma Crt is just a bit brighter as well.

Placing alpha at the western edge of your glasses and moving slightly to the east brings gamma and delta into view: binoculars.

Gamma Crateris is a close binary: 4.1, 7.9, 93, 5.3".


The consellation has two other binaries, both of which can be enjoyed with binoculars.

From the present binocular field move exactly one field northwest: binoculars. Centred now is the wide binary Struve 1509: 7.4, 9.4; 16, 33".

Now move one more field northeast, placing epsilon on the southeastern edge: binoculars. Near the northern edge is BU 600, a multiple system including a binocular companion:
      AB: 6.2, 10.5; 211, 1.3"
      AC: 6.2, 8.2; 99, 53.2".
