Thank you for a great observing run!

Comments: 

RKS0917+2833 and RKS0909+0512: increased exposure time to 1200 s because it was close to moon. The star was plenty bright but the background was a bit high. 

RKS1014+2104: close to moon, background very bright. Still tried it because it was one of Tim's top priorities - increased exp time to 1200 s. 

HIP49442: binary, resolved in CHIRON? I observed A.

RKS1227+2701AB: Resolved in CHIRON. Observed A. 

V5856 Sgr: very tricky to find this one tonight. I'm about 95% sure I got the right one. 

I had to do the queue out of order at the end of the night because of the telescope limits. I don't think that matters to you, but just in case you need to know.
