Primary blue white. Companion very dim. No color noted. Double is set in a busy but dim field. I'm sure that the field would be much brighter without the full moon.

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. Telescope: Celestar 8" SCT Eyepieces: 25mm, 17mm, 10mm Magnification: 80x, 120x, 200x |
A fairly faint pair, especially
the companion, but it is readily apparent and split. The primary is a nice
blue and thesecondary too faint to tell.

Date & Time: 31.07.01. 2120 UT Seeing: 7 <1-10 Seeing Scale (10 best)> Location of site: Near Halifax West Yorkshire, England. Site classification: Suburban Sky darkness: 4.4 (U Mi) <Limiting magnitude> Temperature: 12ºC Conditions: Variable cloud, Wind SW 5 kts Telescope: Orion Optics UK GX250 10" f4.8 Newtonian on Vixen GP mount. Eyepieces: 20mm Plossl, 9 mm Ortho Magnification: x60, x133 |
Easily split in bright twilight
at x60, better at x133. I was a little surprised to be able to see the
magnitude 10 comes with relative ease in these conditions.
No colour noted - too much
light.

At 85x I got both cpn, the
brighter one at about 6" - WWS/W (WDS: 6.0" - 267°), and the fainter
one at about 2' SE (WDS 96" - 140°)
