Easy to Use, Fast, and Accurate

A modular system that can be switched between Ronchi-grating and knife-edge focusing, the Stiletto focuser temporarily attaches to a telescope in place of a camera body (either conventional film or CCD) and allows you to quickly achieve pinpoint focus using a star. Once the telescope is focused, you replace the Stiletto with your camera and aim at your target, whether it be stars and deep-sky objects, a planet, or the Moon

The Series IV is a self-contained unit.   Absolutely no modifications to your own camera are necessary and it is used out of the box.  It attaches to your telescope's t-ring  or adapter the same way your DSLR camera does now. The Series IV has a bayonet mount identical to your camera's.   To achieve perfect focus,  this quick and simple 4-step swap-in, swap-out procedure is followed:
