| Star: Omicron
Capricornius (SH 324)
Location of site: Northern Kansas City, Missouri (USA) 94d 30m west longitude, 39d 15m north latitude 980 ft above Mean Sea Level Date of observations (UT): UT: 02:15 of Sept. 16, 2000 Site classification: suburban Sky conditions: seeing-- 4/10 up to 8/10, in short spans of time transparency-- 8 out of 10 limiting visual magnitude-- 5.0 mag Telescope: Celestron C-8 Eyepiece: 20mm (104x) |
Position: 2030-1835
Magnitudes: 5.9, 6.7 Sep/PA's: 22 = / 239 - Year of last measurement: 1968 Distance (light years): 239 Luminosity (in suns): 29 Eyepiece and magnification: 20mm (104x) Colors noted: Both W, and in a faint field. (But Webb saw them as W and B.) The primary whirls around at 301 kps. Hipparchos/Tycho mission data show different distances for these stars; they may be an optical system. First measure: 21.8" @ 240 (Wilson). I rated the pair 2. Nice choice, Mary (but very difficult for me to pick out of the sky glow of Kansas City). |

Date & Time: 9 p.m local; UT +11. Saturday, September 16th 2000. Seeing: 6/10 <1-10 Seeing Scale (10 best)> Transparency: 6/10 Location of Site: Terara, New South Wales, Australia, Long.150.38 degrees; South 34.52. Site Classification: Suburban Sky darkness: 4.5 <Limiting magnitude> Instrument: 8" F9 Dobsonian Magnification: 72X (25mm K) |
This much-loved double is described in the Observer's
Guide as a 4/6 inch telescope special of Bluish-white and Blue. It lies
in the easily spotted triangle of 10,11 and 12 , with 12 the most Southern
of the three and recently visited by Neptune earlier in the year.
Comments: On this viewing night I noted this a striking equal-looking pair as a Pearl White forming an interesting group with a wide fainter star to the south. This show-piece glowing double makes it a worthwhile Olympic candidate. Ambience: In this special night, while sky clarity was poor, the mild
Spring night air was heavy with the mingling aromas of Banksia-rose,
Jasmine and clusters of Fresias which always spring up each year in unexpected
spots. The rising Moon glowed in the East and the neighbour's dog
howled for human company. Unable to give these special doubles my full
attention ,I eventually pacified him by using the old Sherlock Holmes trick,
but instead of tossing him pieces of meat he was quite content with
a couple of healthy breakfast biscuits. After this magic trip through these
well chosen Olympic Doubles, when I came indoors my wife informed me with
glee that Australia's favourite swimmer had just won two gold medals in
the pool. It was truly a great doubles night.

Date & Time: 9/18/00 8:30 pm CDT Seeing: 8 <1-10 Seeing Scale (10 best)> Location of site: Killeen, TX (Lat 31 N, Elev 600 ft) Site classification: Suburban Sky darkness: 4 <Limiting magnitude> Telescope: Orion 6" Dob. Magnification: 32x, 98x |
Easy to find, a short hop down from alpha and beta. Easily
split at 32x. One of 3 relatively bright stars in a triangular asterism.
The brighter seemed to me to blue and the other yellow.
Separation 20", PA 58.

Using 18mm for 46X, a nice pair emerged with both primary
and secondary white. Olcott saw a "bluish" secondary while Smyth gives
both as "bluish" and states that "It may be assumed, upon the evidence
before us, that o' Carpricorni is an optical object."

The sep. of 21.9” at a distance of 196 light years, corresponds to
1317 Astronomical Units, more than 16 times the diameter of the Pluto’s
orbit
around the Sun. |

I like this one for the setting; at 37x, it's part of a triangle with
rho, a
wide pretty yellow/orange pair, and blue pi, too close (3") to split while keeping them all in the same field. Omicron looked pale blue-white with a more intense blue in the secondary; 80x washed out the color to me. Olympic commentary: An easy tumbling run across the mat . . .

Omicron Capricornius
(SH 324)
Date & Time: 26-September-2000(19:10 UT) Seeing: 5 <1-10 Seeing Scale (10 best)> Location of site: Cheshire. UK 53° 15' N –2º 33' W Site classification: Suburban Sky darkness: 3 <Limiting magnitude> Telescope: 80mm f /5 Refractor. Any Quoted PA or SEP using microguide Magnification: X40, X64
|
No setting circles required to find Omicron Cap as it
is the Southern star of a neat triangle of stars. It was just below
this star I first observed Uranus through
a telescope for the first time a couple of years ago. Using a magnification of X40 a beautiful pair of white stars could be seen against the darkening sky. Using the microguide and X2 barlow lens (X64) the PA between the two was estimated to be 235deg. |
