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.

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' 
component of the system.

Date & Time: August 8 2001 
Seeing: 9 <1-10 Seeing Scale (10 best)>
Location of site: Canada
Site classification: Suburban
Conditions: Clean skies and warm temperatures.
Sky darkness: 4.5 <Limiting magnitude> 
Telescope: 6inch/f5 newt
Magnification: 85x

 

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 ***
