Star    Description
ε Lyr    You have to start with this - no description necessary 😜
ζ Lyr    Bright, wide pair. White and pale green.
Σ2362    An uneven pair. X89 revealed a white primary and greenish secondary
 β Lyr    Brilliant at x42. White primary with a vivid blue secondary
Sh 282    Wide pair, white and blue. X89. There's another pair, optical, in the same field. Didn't try for OΣ525 - didn't have it marked on my chart ☹️
 β 648    Slight elongation - not resolved at x286. Listed as 5.3, 8.0, 1.3"
Σ2461 (17 Lyr)    Bright primary with a faint secondary. Difficult in this kind of transparency
Σ2470 & 2474    Almost a mini double-double at x89. Quite spectacular in its own way
OΣ367    Wide pair with a faint secondary
Sh 289    A wide, easy pair
Σ2481    Close, even pair at x89
Σ2469     Listed as 7.9, 9.1, 1.3". Not split or suspected at x286 - maybe tighter than 1.3"?
Σ2472    Multiple system. All but the primary too faint for these conditions.

A good session then, but spoiled by poor transparency. It's a bit sad when a 102mm can't see mag 10 ☹️
