Historical observation. Not from the official
period for this project.
Located at 1759-3015, and consisting of
a 5.0m K5 giant primary (orange color) and an M0 giant (or supergiant)
7.0m star (deep red) 5" away at PA 106 (slowly increasing). Observed
at 104x, I noted a line of 5 or 6 9m stars that trail away to the SW from
this pair. If the pair is 930 light years away, it is about 800 times
brighter than the Sun. The primary is an infrared source and spectroscopic
binary. It was first measured by John Herschel in 1836 (when he obtained
4.8" at 105 deg). Rated 3.

Mag. 5/7, Sep 5.5". This star is close
to Gamma Sag and
near the border with Scorpio. It is also listed as PZ 6. Comments: This wide double is found in
a field which resembles a wide scattered open cluster. The primary is white
and the companion is Reddish providing a contrast in brightness. Hartung
sees them as

Date & Time: 17 Jul 2001 05:15 UT; 00:15 CDT Seeing: 6 <1-10 Seeing Scale (10 best)>. Transparency: 9/10 Location of site: Merritt Reservoir, NE, USA Latitude: +42° 36´ N Longitude: 100° 53´ W Site classification: Rural Sky darkness: 6 <Limiting magnitude> Telescope: 12.5" f/5 Dobsonian Magnification: 106x |
Seeing was bad at the low (17d) altitude,
and I was unable to see
any black between the pair. I could see the contrast of the red and orange figure-8, however. Striking! |
