Réducteur de focale 0,75X
According to availability at the supplier. Please contact us for more information.
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.
