When is the best time to observe HIP 92831?

HIP 92831 is best observed from May through July, with peak visibility during June when it transits around midnight in the Northern Hemisphere.

Where is HIP 92831 located in the sky?

HIP 92831 lies in the constellation Lyra at right ascension 18h 55m and declination +41° 36′.

What telescope do I need to split HIP 92831?

Splitting HIP 92831 requires an aperture of roughly 60 mm or larger — the components are separated by about 23.9″ at magnitudes near 5.4. The companion is about 6.1 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
