When is the best time to observe HIP 12744?

HIP 12744 is best observed from September through November, with peak visibility during October when it transits around midnight in the Northern Hemisphere.

Where is HIP 12744 located in the sky?

HIP 12744 lies in the constellation Aries at right ascension 02h 44m and declination +25° 38′.

What telescope do I need to split HIP 12744?

Splitting HIP 12744 requires an aperture of roughly 100 mm or larger — the components are separated by about 2.9″ at magnitudes near 6.3. 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.
