Antares and companion

Hi

Here is an LPI image of Antares and its fainter companion taken through my Vixen 4" refractor on a night of outrageously excellent seeing. Antares was at the zenith.

Imaging details:
Vixen ED102S refractor mounted on a Vixen GP-DX mount with Vixen Skysensor2000 GoTo system though a TeleVue 5x Powermate and Vixen 2x Barlow stacked using the Meade LPI CMOS camera.
50 images stacked. Exposure = 0.5 seconds.

Antares details:
Antares is a deep orange, spectral class M1 fireball. Multiple Star System, aka Alpha Sco, 21 Sco. AB: 1.06+5.4 mag, PA 274° Sep 2.54" (2004.5). RA: 16h29m24.5s, Dec: -26°25'55" (2000) in Scorpius Magnitude: 0.91. Distance: 600 +/- 190.0 ly.
Cheers

Dennis
