My interest in astronomy has been for the last 32 years. I enjoy interpreting celestial objects seen in the telescope for people. It is very satisfying to teach people of all ages about our cosmos; it's certainly a very interesting place indeed!
I also enjoy building plastic scale model aircraft and painting them with an airbrush. Making sure the markings and colors are accurate is great fun, it teaches you about history and also gives you a very neat object to place on your shelf at home.
The last two books I read was on the American bombing campaign in Europe by the Army Air Force in WW2. Also, Parallax which dealt with the race in the early 19th century to measure the distance to the first star.
