It is suitable for 5 inch, 6 inch, 8 inch, 9 inch, 11 inch and 14 inch, Schmidt-Cassegrain sct telescopes. The metal structure with two sets of four pieces of full-broadband coating can defocus your telescope to f6.3 without changing the image quality.
This focus-reducing lens correction lens can make the focal ratio of c5, c6, c8, c9.25 become f6.3.
Using this zoom lens can increase the field of view and reduce the exposure time in astrophotography.
This f6.3 reduction lens is a four-element design with full surface coating, and it is very good for both visual and photographic use.
