N Hydrae

Observation Notes:

I was unable to tell which star was the primary, so the PA appeared to be either 203° or 157°. Separation seemed to be about 10 arc seconds. WDS values from 1783 are 210° and 9.3 arc seconds. That's a pretty old measurement, and I'm not sure how close it is to a more modern measurement. But it was close to what I saw. Colors appeared as white for the northeast star, and pale yellow for the southwest star.
