The reducer shortens the focal length of the telescope and is therefore also called a focal reducer. This makes the optics "faster" for photography and the image brighter. It also increases the field of view.
Since a stronger signal is captured in the same exposure time with a reducer, you can expect a higher signal-to-noise ratio and thus better detail in your images.
Installing this reducer is quick and easy. First, remove the four piece photographic adapter from the Askar FRA400C by rotating it counterclockwise. Next, remove the dust cap on the reducer, and screw it onto the rear of your telescope. Attach your imaging equipment to the M48 male threads of this reducer, ensuring your camera sensor is 55 mm away for proper focus. You?re now all set to image!
