CrB doubles

Last night was pretty special.  About as perfect seeing as I've ever had; hardly any diffraction and sometimes just steady disks.  Plus an amazing surprize double-double.  Really great and satisfying session.  And I finally saw the owl who often screeches in the sky above me, but I never had a glimpse of before!

STF 1936.  552x.  Pretty faint near equal wide white pair through finder.  In scope one star splits into a close double

STF 2011.  552x.  White and reddish 3 delta mag, ~2".  Other stars in the field might be part of a system

HIP 79010, 16h08m21.1s,+28°57'21",CrB,9.5,77°

STF 2022.  552x.  Yellow orange and blue pair.  B is much fainter, 3-4 delta mag, ~1.5"

SAO 64640, 15h20m55.7s,+30°38'23",CrB,10.0,71°

STT 302.  552x.  Seems to be a triple star.  One pair fainter and pretty close, 2”.  Brighter star much further away, and a triangle with a medium bright star.

STT 302B, 15h55m38.9s,+34°19'24",CrB,10.1,79°

Zeta 1 CrB, 15h40m01.9s,+36°35'14",CrB,5.9,76°

STF 1964 & HU 1167.  552x.  At first only noticed the fainter pair, the Struve, a near equal pair about 3" separation.  Brighter star further separated suggested it was in the system.  Then seeing became perfect, and I noticed a much fainter pair to the bright star, reddish color, about 1" separation, 3-4 delta mag.  Yes!  A double double.  Magnificent.
