Seeing was decent last night.  I want to share these three pairs I observed in Cygnus with my 6" f/8 apo.

 

STF 2496 m1=6.5 m2=10.0 sep 2.1" PA 81 deg.  I saw this one with great difficulty using a 4mm UWAN at 304x, but confirmed the PA as east, slightly N before looking at the PA in the database.

 

STF 2511 m1-9.5 m2=11.1 sep 7.2" PA 53 deg.  I used 304 x on this one also, because it was already in the scope.  It was best seen with slightly averted vision.

 

STF 2555 m1=9.4 m2=9.9 sep 1.8" PA 283 deg.  Again used the 4mm UWAN at 304x.  This one was only a bit difficult due to faintness.

 

I had to stop soon after the above due to fog starting to roll in.
