Location of site: Killeen, TX, USA Site classification: Suburban Sky darkness: 4 <Limiting magnitude> Temperature: In the 80's F (30's C). Slight breeze.

Fairly wide but the secondary is quite faint. However at mag 10.4, it is still quite visible. The primary is white but the secondary to faint to tell. | |||

Date & Time: 13th July 2001 2145 UT Seeing: 7 <1-10 Seeing Scale (10 best)>. Location of site: Near Halifax West Yorkshire, England. Site classification: Suburban Sky darkness: 5 <Limiting magnitude> Temperature: 14C Conditions: Light W'ly breeze, 1/8 cloud Telescope: Orion Optics UK GX250 10" f4.8 Newtonian on Vixen GP mount. Magnification: x60, x133 Eyepiece: 20mm Plossl, 9mm Ortho |
Observed whilst still in
nautical twilight. Was able to see the primary (mag.7.7) in the x10 finder,
but needed x133 and averted vision to identify the comes in these light
conditions.
At this time this was seen
as a very ordinary pair. No coloration noted. Perhaps more interesting
in a dark sky. I shall re-visit to see.

Date & Time: 19 July 2001 ( 21:45 UT ). Seeing: 6+ <1-10 Seeing Scale (10 best)>. Location of site: Barreras, Salamanca, Spain. Site classification: Rural,Suburban. Conditions: no moon, fairly dry but with gusts of wind. Sky darkness: 5+, some light due to street lights in the village. <Limiting magnitude> Telescope: Meade 7" Mak Cas mounted on a Losmandy GM8. Eyepieces: 20mm plossl, 12mm plossl Magnification: 134X and 223X Harshaw Scale: <1-5; 1 best> |
Hint of the double at 134X but a good split at 223X. With the big difference in magnitudes and the bad seeing the secondary was oscillating in and out of view but the split was definite. The primary was white with a tint of violet and the secondary was a whitish grey. With the color tints and the difference in magnitued I gave this double a rating of 2. | |||

With a Lucida showing its
old star pedigree, markedly orangish, though resolved at 40x, the cpn was
dim and remained so even at 85x. Very nice field though; a ***
