WebA flattener/reducer will usually have a diameter of 2″, and can be inserted into the eyepiece opening of the focuser drawtube. Step-by-Step Instructions First, remove the camera lens that is currently mounted to the body of your DSLR. WebA focal reducer works using a positive lens, which shortens the focal length by causing the incoming beam of light to converge more quickly. The shorter the focal length, the greater the focal reducer’s reduction factor when placed into a telescope’s optical path. This also decreases the effective focal ratio of the instrument.
