An attractive uneven pair. Primary showed burnt yellow. Secondary no colour Split at 50X studied at 100X

An odd double. The primary seemed brighter and yellower than the published material would suggest. Although a KO spectrum it seemed to me to be closer to G3 or 4. I suspect Its almost half a mag brighter than the published 6.4.
Found the star to be a very awkward star hop from the end of the belt.
