Special Object:

CYGNUS

CH Cygni



Even professional astronomers are keen to hear news of the behaviour of this unpredictable star. It is a double system made up of a large pulsating red star and a smaller blue one. Gas passing between them sets off 'nova-like' eruptions. The bright star to the left is theta Cyg, and CH is marked with a crosshair.
