Lambda Aquarii is best observed from July through September, with peak visibility during August when it transits around midnight in the Northern Hemisphere.

Where is Lambda Aquarii located in the sky?

Lambda Aquarii lies in the constellation Acquario at right ascension 22h 53m and declination -07° 35′.

What telescope do I need to split Lambda Aquarii?

Splitting Lambda Aquarii requires an aperture of roughly 1040 mm or larger — the components are separated by about 0.6″ at magnitudes near 3.7. The companion is about 4.6 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
