laser pen mount

Everyone into astro-photography knows how difficult it can be to aim a camera at a nearly invisible object in the dark sky, even knowing where it should be. Andromeda is high in the sky in winter and even looking through the viewfinder of my camera is almost impossible. A laser pointer is easy to use so I made this bracket to attach to my camera.
