Making the exposure is challenging enough, but to make a difficult task even harder, the large camera must be mounted on a clock driven equatorial mount to keep the stars from trailing. Keeping a large camera on track as the Earth turns can be supremely difficult; as the clock driven mount moves the camera and lens across the sky, Danny makes small adjustments to the tracking while looking through a guide scope to keep stars in perfect registration as the film is exposed.

Although shot in a fairly light polluted sky, Danny's image gives us a tantalizing hint of what is possible when a seldom used method is given a chance to show what it is capable of. Danny is working on refining the process and hopes to get out under a clear dark sky when the opportunity arises!
