Something to image in the strong moonlight. Mizar (Zeta Ursae Majoris) has 2 partners: the brighter one you can see is 14 arcsecs away at mag 4 but there’s also one at 0.04 arcsecs separation and mag. 2 that we can’t see separately. Alcor is a binary too with an 8th magnitude red dwarf companion, 1 arcsec away from the primary.
