Looks very much like a "Little Lyra". Very rich field. Double set at NE corner of a parallelogram that looks very much like a miniature Lyra (at least through the reversed field of a SCT.

Split but not very cleanly
at 26x. A clean split and nicer image at 46x. No colors noted in either
component.

Spent a long time looking
for this one. First of all drifting cloud obscured the area and then I
got myself in a knot over the visual aspect of the position angle. I had
the right star but refused to believe it and foolishly continued searching.
When I eventually put this
right I enjoyed the two blue stars, one rather paler than the other and
in particular the fact that the system is part of a nice little rectangular
asterism in a pleasant field of faint stars. Burnham shows nearest of these
to be the 'C'

For some strange reason,
I double the estimated sep. while checking it at 85x. But a nice catch
with a bit of colour contrast, silver/blue-grey. An easy ***
