I have just very recently started dabbling in astrophotography. I am by no means an expert at this genre of photography, but I am having a bit of fun with it. I recently purchased a wide-angle lens which has been great for photographing the heavens. (It works really well for photographing tunnels too, which all of you know is a major hobby of mine). On one occasion in Texas, I decided to try capturing the constellation Orion. Admittedly, this is not my best photograph, but it was part of a learning experience. I happened to capture an airplane in the photograph. You can tell that it is an airplane due to the flashing blue and green lights.
