Description:
A challenging pair with a DI of 92.6. Just a hint of elongation at low power which was more noticable at mid power. At high power I was able to make out the faint companion - a tiny dot just off the main component. The primary was white, and not much could I tell about the color of the companion. The FOV was otherwise rather sparse.
