When is the best time to observe HIP 93053?

HIP 93053 is best observed from May through July, with peak visibility during June when it transits around midnight in the Northern Hemisphere.

Where is HIP 93053 located in the sky?

HIP 93053 lies in the constellation Draco at right ascension 18h 57m and declination +62° 24′.

What telescope do I need to split HIP 93053?

Splitting HIP 93053 requires an aperture of roughly 60 mm or larger — the components are separated by about 17.4″ at magnitudes near 6.5. The companion is about 3.2 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
