Delta Corvi Date & Time: 03/03/2004, 0:42 AM UT Seeing: 5 <1-10 Seeing Scale (10 best)> Transparency: <1-10 Scale (10 best)> Location of site: Rio de Janeiro, Brazil (Lat 22°54´ S, 43°14´ W, Elev 700 m) Site classification: Forest Conditions: Temperature: 20°C Humidity: 60% Sky darkness: 4.5 <Limiting magnitude> Telescope: 83mm refractor (f/14.7) Eyepieces: Magnification: 38x, 45x and 78x |
Despite of 5.5
magnitude
difference, could split it at 38x. Splitting was easy in all
magnifications.
Components are 3.0 and 8.5 and separation is 24.1" at position angle of
216 degrees. Blue and white components.

This is
another stellar triplet with the companion stars wide. Two Blue
companions accompany the White primary at low power. HS2.

A hefty
difference in magnitude, it was split at 98x and showed to me stars of
yellowish-white and white. Rated 3E.

Although small, Corvus is
very
easy to identify and one of the most symmetrical patterns in the sky.
From my latitude is visible in the zenith now. This constellation has
the honor to include one of the most famous double in the sky, Delta.
In the New Handbook of the Heavens selected pairs list, is described as
"yellow and lilac, a beautiful and easy pair". However, I see both
stars pure white or slightly bluish. Easy split at 32x and 54x.
