Arcturus- A Bright, orange star
Vega- A bright, blue-white star
Sirius- A bright white star, the brightest in the sky at a distance of 8 light years.

A question mark after an object we have listed means that it is becoming very difficult to see because it is near the horizon and/or at the limit the telescope can resolve it (see it clearly.)
The list of objects mentioned for each date may be modified due to viewing conditions.
Just as our eyes cannot see through clouds, our optical telescope cannot either. We make every effort to stay open, but nature sometimes has different plans for the night sky. Please check the sky conditions before you travel to visit us.
