When is the best time to observe HIP 3083?

HIP 3083 is best observed from August through October, with peak visibility during September when it transits around midnight in the Northern Hemisphere.

Where is HIP 3083 located in the sky?

HIP 3083 lies in the constellation Cassiopeia at right ascension 00h 39m and declination +49° 21′.

What telescope do I need to split HIP 3083?

Splitting HIP 3083 requires an aperture of roughly 60 mm or larger — the components are separated by about 12.5″ at magnitudes near 5.4. The companion is about 5.1 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.

Apparent motion is significant on a human timescale — worth revisiting in a decade.

Measured from the WDS observational archive. No orbital solution has been derived — most likely the period is too long to fit an orbit to the available measurement arc.
