When is the best time to observe HIP 112449?

HIP 112449 is best observed from July through September, with peak visibility during August when it transits around midnight in the Northern Hemisphere.

Where is HIP 112449 located in the sky?

HIP 112449 lies in the constellation Grus at right ascension 22h 47m and declination -46° 56′.

What telescope do I need to split HIP 112449?

Splitting HIP 112449 requires an aperture of roughly 60 mm or larger — the components are separated by about 10.4″ at magnitudes near 6.6. The companion is about 3.3 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
