The weather last night decided to clear after all:

 The bright star at the bottom between the pair of horizontal red lines is Arcturus, Then

Comet Lemmon, naked eye bright blue-green with a visible tail. Higher up

is a trail which I suspect is a reflection off one of the 50 or so Starlink satellites visible at any one time in twilight, 4th mag or so for many. 

The top red line points down, leftish to R CrB, the star that fortuitously brightened enough in 1967 for Vicki to identify regular or semi regular variability at near maximum light for her MSc.
