When is the best time to observe Lambda Columbae?

Lambda Columbae is best observed from November through January, with peak visibility during December when it transits around midnight in the Northern Hemisphere.

Where is Lambda Columbae located in the sky?

Lambda Columbae lies in the constellation Taube at right ascension 05h 53m and declination -33° 48′.

What telescope do I need to split Lambda Columbae?

Splitting Lambda Columbae requires an aperture of roughly 960 mm or larger — the components are separated by about 1.0″ at magnitudes near 4.9. The companion is about 5.6 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
