Taken at 10pm on Sunday 13th July, 2014 with a full frame Nikon D3 and Nikon 70-200 f/2.8 VRII + 1.4x Teleconverter

280mm - f/4.0 - 1/20sec - ISO 250, hand held out of an upper back window!

RAW file processed in Adobe Lightroom.

Can you see the star to the upper right above the moon...?


It is: Alpha2 Capricorni (α2 Cap, α2 Capricorni),a star in the constellation Capricornus.

It also has the traditional star name Secunda Giedi or Algiedi Secunda, and shares the name Algedi (from الجدي - al-jadii, meaning the goat).

Alpha Capricorni (α Cap, α Capricorni) is an optical double star in the constellation Capricornus. It has the traditional names Algiedi, Al Giedi, Algedi or Giedi; however, Giedi is sometimes also associated with β Capricorni.

The name Algedi is derived from the Arabic word الجدي al-jady, meaning "the billy goat" or "kid," and also refers to the entire constellation of Capricornus. It is known as 牛宿二 (the Second Star of the Ox) in Chinese.

The two unassociated star systems in the optical double are:

α¹ Capricorni, also called Prima Giedi
α² Capricorni, also called Secunda Giedi
They are separated by 0.11° on the sky, and resolvable with the naked eye, similar to Mizar and Alcor.
