0.75x Focal Reducer for GSO Ritchey Chretien OTA

Details

The GSO 0.75x Focal Reducer for RC OTA effectively reduces our GSO Ritchey Chretien Telescopes from f/8 systems to f/6 - increasing the apparent field and reducing exposure times accordingly.  Highly recommended for these scopes, this 0.75x reducer also assures flat field and round stars edge to edge.  

This Reducer has a practical spacing distance of 80mm (+/-5mm) from the rear element to imaging chip, giving the user more than enough space for off-axis guiders, filterwheels and other accessories. 

Also recommended for use with the GSO/Altair Astro RC systems.
