Description:
This pair has me confused. At low power there was not much sign at all of duplicity, at mid power I thought I could get an occasional glimpse of the secondary, which was confirmed at high power. However, unless I was totally disoriented, it was in the opposite quadrant from where it should be, being to the SW rather the the NE. Later on I had occasion to examine a DSS plate of this. It appears what I saw was a field star located near the line of sight and that I was not able to observe the true companion.
