When is the best time to observe HIP 7016?

HIP 7016 is best observed from September through November, with peak visibility during October when it transits around midnight in the Northern Hemisphere.

Where is HIP 7016 located in the sky?

HIP 7016 lies in the constellation Sculptor at right ascension 01h 30m and declination -26° 12′.

What telescope do I need to split HIP 7016?

Splitting HIP 7016 requires an aperture of roughly 240 mm or larger — the components are separated by about 3.2″ at magnitudes near 5.9. The companion is about 5.1 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
