Not sure if you guys were here when we had the "Monthly Observing Challenge". The files are still available and I have posted a link to them. I selected the double stars and did the write ups for them. If you haven't observed these doubles before they are all really nice. Several have a lovely colour contrast. If your interested in Double/Multiple stars, these are worth observing now and in the coming months and suited to smaller/medium apertures. Here they all are with a link to the page contining the write ups:-

May 2005 - X Velorum (Dunlop 95) in Vela

June 2005 - 24 Comae in Coma Berenices

July 2005 - HN40 at the heart of the Trifid Nebula in Sagittarius

August 2005 - Gamma Delphinus

September 2005 - h5003 in Sagittarius

October 2005 - Rho Ophiuchus in Ophiuchus
BTW Mike is the one who spells "Ophiuchus" incorrectly in the Challenge notes, com'on Mike learn to speeellll thats an easy one

November 2005 - Theta Eridanus (Acamar) in Eridanus

December 2005 - Sigma Orionis in Orion

Another very nice double worth taking a look at which is currently nicely placed early evening is h3945 in Canis Major. This is a really nice bright yellow/blue double and not too dissimilar visually to X Velorum only it's not quite as bright being about Mag 4.5. It is about 2 degrees south of a nice open cluster in NGC 2362.

There are also 4 or 5 nice orange/blue doubles within about 3 degrees of X Velorum. Not as bright but still nice and easily separated at about 60X to 80 X with medium aperture. Not sure of their names (I think 1 is Dunlop 89) but they are easy to find by just panning in a line between Eta Carina and the Gem Cluster
