Portrait of our observatory as rendered by artist Les Leffingwell, who as you can see is a very talented and award winning artist. He contacted the Observatory Director for permission to use the grounds and painted this image over two days.  We like the result!   Click here to see more of his work.   

Super Moon? The full moon on August 10th was called the supermoon, but as you can see from the images above, it's misleading.  These three images represent the moon at it's largest (the so-called super), it's average, and smallest sizes.  To the naked-eye, it's hardly noticeable. Read about it in Astronomy Magazine.
