M45 aka the Pleiades (The Seven Sisters)

Last night I finally got some fairly clear skies here in sunny Arizona so I decided to capture this picture of the Pleiades which is normally an optimum winter object but I am a night bird so staying up late to get objects ahead of time is no real bother. Except maybe in the morning.

The stars in the Pleiades are thought to have formed together around 100 million years ago, making them 1/50th the age of our sun, and they lie some 130 parsecs (425 light years) away. From our perspective they appear in the constellation of Taurus, with approximate celestial coordinates of 3 hours 47 minutes right ascension and +24 degrees declination.

I also took my first crack at a portion of the Veil nebula in the constellation Cygnus the swan. The Veil nebula is a supernova remnant that occurred about 5 - 10,000 years ago. It is located around 1,400 light years away.
