When is the best time to observe HIP 46225?

HIP 46225 is best observed from January through March, with peak visibility during February when it transits around midnight in the Northern Hemisphere.

Where is HIP 46225 located in the sky?

HIP 46225 lies in the constellation Carina at right ascension 09h 25m and declination -61° 57′.

What telescope do I need to split HIP 46225?

Splitting HIP 46225 requires an aperture of roughly 80 mm or larger — the components are separated by about 8.8″ at magnitudes near 5.8. The companion is about 3.8 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
