When is the best time to observe HIP 82350?

HIP 82350 is best observed from April through June, with peak visibility during May when it transits around midnight in the Northern Hemisphere.

Where is HIP 82350 located in the sky?

HIP 82350 lies in the constellation Hercules at right ascension 16h 50m and declination +13° 16′.

What telescope do I need to split HIP 82350?

Splitting HIP 82350 requires an aperture of roughly 100 mm or larger — the components are separated by about 4.9″ at magnitudes near 5.9. The companion is about 4.1 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
