doubly ionized oxygen (O III) and the ionized sulfur (S II)

The flattener is suitable for several apochromatic refractors with a focal ratio between f/5 and f/9

The TS Optics 2x ED 2" Deluxe Barlow lens is high quality yet affordable and features an ED (extra low dispersion) element for better colour correction and contrast

The Sony IMX174’s global shutter function provides improved image quality for moving objects of fast image distortions caused by poor seeing

GSO 8" f/4 CARBON IMAGING NEWTONIAN OTA greenline doubly ionized oxygen (O III)The 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
