Columba

COLUMBA the Dove is a small constellation that can be seen in the night skies of both Northern and Southern Hemispheres. It is west of Caelum, southeast of Canis Major (the Big Dog), south of Lepus, north of Pictor, and east of Puppis. The brightest star is named Phact; it is also called Alpha (α) Columbae and has an apparent magnitude of 2.65. Wazn, also known as Beta (β) Columbae, is the second brightest at magnitude 3.2. Ignoring the convention of the Gamma star being the third brightest in many constellations, Delta (­δ) Columbae is the third brightest with a magnitude of 4. NGC 1851 is a spectacular globular star cluster to the east of the constellation.
