Another good test, equal magnitude (9.3), faint and close (1.4). I had to exam several possible candidates in the same FOV before I identified this. There was little if any evidence of duplicity at low power, at mid power I got elongation, and I was able to split this, if barely, at high power. Overall this pair appeared yellow. It is part of a 4 star asterism, a triangle with an appendage just off the corner formed by this pair.
