Procyon is a bright star, easily located to the east of Orion. Use the two stars of his shoulders – Betelgeuse and Bellatrix – to help identify it.
Through the finderscope (or binoculars) it appears as a brilliant white star with a wide, faint blue-white companion nearby. This companion appears about ten times fainter than Procyon itself.
The pair will still appear within the same field of view at 35x but you’ll also notice a scattering of many fainter stars in the background. In particular, look out for another faint star near Procyon and two others near the companion.
Procyon is the brightest of only two bright stars in the constellation of Canis Minor, the Little Dog. As with Sirius, the brightest star in Canis Major, the Great Dog, it follows Orion across the sky, just as the two dogs follow their master as he embarks on his winter hunting trips.
(They all seem totally oblivious to their prey, Lepus the Hare, which can be found below Orion. Maybe they’ve been distracted by Taurus the Bull, charging from the west.)
Again, like Sirius, Procyon is another bright, white star with a white dwarf companion that’s just under eleven and a half light years away. The pair orbit one another every forty years.
