When is the best time to observe HIP 117510?

HIP 117510 is best observed from August through October, with peak visibility during September when it transits around midnight in the Northern Hemisphere.

Where is HIP 117510 located in the sky?

HIP 117510 lies in the constellation Sculptor at right ascension 23h 50m and declination -25° 20′.

What telescope do I need to split HIP 117510?

Splitting HIP 117510 requires an aperture of roughly 60 mm or larger — the components are separated by about 13.7″ at magnitudes near 6.4. The companion is about 5.2 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
