Tegmine is an easy split with decent conditions, a gulf of dark beween the 5" ζ1 Cnc and ζ2 Cnc pair, ζ1 Cnc itself is just barely split in moments of good seeing, the ζ1Cnc B companion visible 1.6" to the northeast, ζ1 Cnc and ζ2 Cnc are both pale yellow
This trio (and unseen companions) is a gravitationally bound system, Gaia EDR3 data shows matching parallax and high proper motion...parallax PM RA δ
