The equipped 0.75x focal reducer enable you to get a wider field of view. It helps to increase the maximum 
aperture to 1 stop. Photographically this will enable you to reduce your exposure time and still capture the 
same amount of light. Therefore, the screen will display the equivalent aperture(T), instead of aperture(f) . 
For example, if the aperture is set at f4, DEC LensRegain will display T2.8.
