Only for use with F/4 Newtonian scopes. 

The Skywatcher F4 Aplanatic Coma Corrector is designed to eliminate the vignetting that occurs on Newtonian telescopes, allowing you to pinpoint stars in the scope's field of view. It retains the scope's magnification and is optimised for F/4 Newtonian reflectors, such as the Quattro series. By eliminating coma aberrations, it delivers sharp and precise star images across the entire field of view, preserving the telescope's original magnification. 

This coma corrector incorporates a four-element optical system, including one element made from FPL51 extra-low dispersion (ED) glass, enhancing color correction and overall clarity. It is designed to work with a back focus distance of 55mm and has a M48 thread and 2-inch (50.8mm) diameter, making it compatible with standard 2-inch focusers. Additionally, it includes threads for 2-inch filters. 

The Skywatcher F4 Aplanatic Coma Corrector features M48x0.75 thread for convenient and secure integration with a wide range of M48 cameras and accessories.
