That really bright star in the South is Sirius. To its right, more to the West, you’ll see the three belt stars of Orion. From there, you should be able to determine the shoulders and knees that make up the rest of the constellation. Note the difference in color between Betelgeuse (red) and Rigel (blue).

Here is a list of things you should be able to see in Winter with just ordinary binoculars (7 x 35).

You can use this diagram as a guide. It can be downloaded at The orientation for the map is set for South, with the middle of the circle representing straight overhead. Turn the map upside down when looking North.

The larger the blob on the map, the brighter the object will appear in the sky–note the magnitude legend at the bottom right of the map. Contrary to intuition, the higher the magnitude number, the dimmer the object appears.
