When is the best time to observe HIP 94398?

HIP 94398 is best observed from June through August, with peak visibility during July when it transits around midnight in the Northern Hemisphere.

Where is HIP 94398 located in the sky?

HIP 94398 lies in the constellation Telescopium at right ascension 19h 13m and declination -50° 29′.

What telescope do I need to split HIP 94398?

Splitting HIP 94398 requires an aperture of roughly 80 mm or larger — the components are separated by about 7.2″ at magnitudes near 6.1. The companion is about 4.8 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
