Great pictures. Looking at the second picture, the large reddish star near the bottom is Betelgeuse, part of the Orion constellation. You can see his 3 star belt to the right. Orion is hunting Taurus the Bull. If you scan up from Betelgeus you will see the bright red eye of the bull, Aldebaran. Continuing upwards, you will see the cluster Pleidades, the seven sisters. Finally, if you on the left side of the image, the 2 bright stars are Castor and Pollux, the twins of the constellation Gemini.
