Pinwheel Galaxy

This shot of M33 (Messier catalogue number 33), the Pinwheel Galaxy, by prime focus (using the telescope as a giant telephoto lens) was taken using a home-built 8" f/6 Newtonian telescope. The exposure took 30 minutes using Kodak Tri-X film. It is worth noting that not only the telescope was home-built, but the mirror for the telescope was also home-built and ground and polished by hand.
