Capella is the brightest star in Auriga constellation. It is very easy to spot in the Northern hemisphere. It is a circumpolar star, very bright one. The picture has been taken through a 300mm telephoto lens and Canon EOS 450d over a Sky Watcher EQ6 equatorial mount.

Here it is the full frame, with a lot of stars in the field and great detail:

Looking for Sirius B

Sirius is a difficult binary system, hard to resolve. I am trying it, and I have got one image that shows a dim star very near to Sirius A, but I think it isn’t Sirius B. I have been trying to find out which is the name of the star. I still don’t know it. Searching in Internet (and star atlas) other images of the area I see the star exists, but with no name so far. Here are the sources found:

Procyon, alfa Canis Minor

Procyon is a very bright star near Sirius. For testing purposes, I took a series of shots through my Vixen 12×80 binoculars. Using the shift-and-add method, also known as “image-stacking“, I could spot magnitude 10 stars near Procyon. I didn’t use any tracking, not even manual tracking.
