a Canum Venaticorum


Alpha Canum Venaticorum is ‘Cor Caroli’, the heart of Charles (King Charles II probably).

Having moved half-way along the line from Arcturus to gamma UMa, one should have this view. In the same region is M94, a spiral seen nearly face-on and appearing very comet-like in small telescopes. It's 14 million light years away.

Alpha CVn is a fine fixed double system: 2.9, 5.6, the brightest (and therefore the primary) being alpha2. The companion, alpha1, is found at a position angle of 228º and a separation of 19.6".
