Xi Bootis (Struve 1888) | Main | Schiller and Bayer Craters

Epsilon Bootis (Struve 1877)

Observation Notes:
This was an awesome pair! There is a brilliant orange-yellow primary with a rich Levi's blue secondary hugging it. The seeing made it hard to tell, but the first diffraction rings either overlapped slightly or were close to touching. I'll need to remember to come back to this one.
