22. Observing Star Patterns using Stellarium Orion Canis MajorGemini Canis Minor

23. CANIS MAJOR Is also know as the “BIG DOG.” It contains the brightest star in the sky SIRIUS which is sometimes called the DOG STAR. Observing Star Patterns - CANIS MAJOR

24. Locating Canis Major Look SOUTHEAST find SIRIUS It is in CANIS MAJOR We also observe Betelgeuse and Rigel in Orion and Procyon in Canis Minor SE

25. Observing Star Patterns - ORION ORION is a very easy to recognize constellation that is visible from both the northern and southern hemisphere. It has two very brilliant stars RIGEL and everyone’s favorite star BETELGEUSE (reddish color). It contains the naked eye visible nebula M 42. It appears as the middle “star” of Orion's sword.

26. The naked eye visible nebula M 42. New stars are being formed in this region that is 1,500 light years distant. This is also called Messier 42 “The Great Orion Nebula.” ORION

27. Locating Orion Look SOUTHEAST Find SIRIUS It is below ORION In Orion we observe Rigel Betelgeuse and the three stars that form the “BELT” of Orion SE

28. Observing Star Patterns - GEMINI GEMINI the twins contains the two “twin stars” CASTOR and POLLUX. It is near the star PROCYON in CANIS MINOR which is know as the “LITTLE DOG”. To the right of Gemini is Betelgeuse

29. Locating Gemini Look SOUTHEAST find SIRIUS it is below and to the right of GEMINI We also observe Rigel and Betelgeuse in Orion and Procyon (in CANIS MINOR) SE

30. This completes the basic instructions on how to use Stellarium It might be helpful for you to review this presentation several times to get familiar with Stellarium You may address any questions/suggestions to taasdee@comcast.net Clear skies!
