What is a focal reducer for a telescope? Focal Length of a Telescope: In general, the longer the focal length of a telescope, the smaller the section of the sky it is able to see. This is ideal when looking at distant, dim objects, but makes it difficult to view larger objects such...

If the focal ratio (the f-stop, or aperture) of your lens or telescope is closer to the F/2 range, you’ll have many more options when it comes to settings and the way you approach your target. A “faster” optical system means you’ll be able to collect more signal in a single...
