A nice triple system, forming
a very long scalene triangle. The primary and the fainter and closer companion
point to another double, which I think may be Tycho 3120-492-1 and -2.
If so, then again this is an optical pair. There is also an extremely faint
star, maybe about mag 12 or 13, lying between these 2 pairs, which does
not show up on my charting program.

A very nice group of stars!
An asterism or a real multiple system, or a combination of both, I don't know, but it certainly looks good. There are five stars in a figure which is very much like the constellation Serpens (western part). The brightest star (tail) has a nice deep-yellow color. The eyes of the serpent are two mag. 10 stars, 6" apart. I am a bit puzzled by the
descriptions of Richard and William because the faint star in between was
not that faint to me, it was not bright but obvious at 93x and very clearly
present at 187x. Skymap, using Tycho, gives mag. 10.7 for this star.

Came across as a mini-scutum
at 85x. Got the estimate quite right again for CD, putting it at 7" - SES/SE
(WDS: 6.3" - 294°; 1831, 1967), and making a nice cat's eye.
