Hello!

The Greeks pictured Gemini as the twins Castor and Pollux. While Castor's father was the king of Sparta, and was mortal. Pollux was the son of the king of the gods Zeus, and was immortal, but they both shared the same mother, Leda, queen of Sparta. (it was said that Helen of Troy was their sister).
The two joined Jason and the Argonauts on their search for the golden fleece.

Gemini is home to a number of large stellar 'OB' Associations. An O-B Association is a large, very loose form of an open star cluster consisting of young spectral type "O" and "B" stars. They cover large volumes of space, are loosely held together by gravity and have short lifetimes of a few million years.

To view a sketch of a specific OB Association:
Click on the location of the object on the imagemap or select from the list below.



All sketches were made with an 80mm refractor spotting scope using low-power eyepieces, with an amici prism giving a corrected field of view. To view the sketches of these OB Associations, select from the list below:
