Then place the mask over the front aperture of your telescope by “hanging” it on the plastic screws from the front dew shield. Take a short exposure. The image of the star will show diffraction spikes. The “center” set will most likely be shifted to one side or the other. This is showing the defocus.\u003cbr\u003e\u003cbr\u003eAdjust the focus of the telescope and re-expose the star, once again showing the diffraction spike pattern. Iterate the process until the central diffraction spike is centered against the star and the other spikes. When a symmetrical pattern is achieved, the best possible focus is then reached. Simply remove the mask, center the target object and take amazing, sharp images!\u003cbr\u003e\u003cbr\u003eFarpoint manufactures this \"lifesaving\" astrophotography tool out of virtually indestructible ABS plastic, which comes in two major types and in a range of sizes.
