While messing with some images of M45 I knocked up this image of Alcyone.

This is an easy to find and view multiple star.

Alcyone is an eclipsing binary plus three other companions.

Alcyone A is two blue/white giants seperated by the approx distance of Jupiter is to the Sun.

Not possible to split this pair.

Alcyone B and Alcyone C are both mag 8 white dwarfs and are separated from A by 117 and 181 arcsecs respectively.

Alcyone D is a yellow/white dwarf at mag 8.7 seperated by 191 arcsecs from A.

Image is a crop taken from a wide image of M45 with...

SW 80ED Pro+flattener+Hutech LP filter......Canon 600D 30secs@iso1600

Nice pic of a very pretty area of the sky. I particularly like the chain of stars below Alcyone, known as Ally's Braid (ie Alcyone's Pigtail), across the puddle.

Nice one Mike,

I suppose messing with images is all we can do without clear skies!
