Where is Nu Canis Majoris located in the sky?

Nu Canis Majoris lies in the constellation Großer Hund at right ascension 06h 38m and declination -18° 14′.

What telescope do I need to split Nu Canis Majoris?

Splitting Nu Canis Majoris requires an aperture of roughly 380 mm or larger — the components are separated by about 1.2″ at magnitudes near 4.4. 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.
