GSO 8" f/4 CARBON IMAGING NEWTONIAN OTA greenline Optical design Apochromatic Quadruplet air-spacedThe GSO 8" f 4 Carbon Imaging Newtonian is a fast, compact reflector telescope designed for deep sky astrophotography. The newly updated linear bearing focuser is natively compatible with the ZWO EAF electronic focusing motor. Compared to a common f 5 Newtonian, the photographic exposure with an f 4 system is 40% shorter, making it a great time saver. This instrument is ideal for astrophotography and when used with an additional coma corrector, will
