Historical observation. Not from the official
period for this project.
From 1909-3348, we have a decent triple made up of an 8.1m F5 primary (white), a 9.1m F5 companion (bluish-white) and a companion to the companion (10.5m star of undetermined color). The AB pair is 12" apart in PA 255, while the Bb pair is 6" apart in PA 322. It was observed at 83x, and all three stars show similar proper motions. It is probably abou6 408 light years away, making it a total of 11 times brighter than the Sun. Rated 3.

Mag.8/9.1, 11.8" Sep. This star lies halfway
between Zeta Sag. and graceful curve of Corona Australis. It can be stumbled
across within a group of equally faint stars since it forms an eye-catching
pair.
Comments: A rich field enhances this delightful
pair of Bluish and Pinkish stars. The brighter stars in the field have
the appearance of an open scissors.
