When is the best time to observe HIP 23753?

HIP 23753 is best observed from November through January, with peak visibility during December when it transits around midnight in the Northern Hemisphere.

Where is HIP 23753 located in the sky?

HIP 23753 lies in the constellation Camelopardalis at right ascension 05h 06m and declination +54° 24′.

What telescope do I need to split HIP 23753?

Splitting HIP 23753 requires an aperture of roughly 80 mm or larger — the components are separated by about 7.0″ at magnitudes near 7.2. The companion is about 4.6 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
