When is the best time to observe HIP 48835?

HIP 48835 is best observed from January through March, with peak visibility during February when it transits around midnight in the Northern Hemisphere.

Where is HIP 48835 located in the sky?

HIP 48835 lies in the constellation Vela at right ascension 09h 58m and declination -48° 25′.

What telescope do I need to split HIP 48835?

Splitting HIP 48835 requires an aperture of roughly 60 mm or larger — the components are separated by about 14.1″ at magnitudes near 6.0. The companion is about 4.0 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
