Newton Quattro optical reflector tube 250/1000 f/4
The Newtons have always been the best-selling reflector telescopes in those that combine high diameter at an affordable price. The Newton Quattro 250/1000 f / 4 from Sky-Watcher is a 250mm diameter and 1000mm focal length telescope particularly suitable for photographic use, thanks to the fast f / 4 focal ratio and to the compatibility of the optional coma corrector AO-SUPERCOMACORR .
This instrument is very bright and allows you to record the faintest details of weak objects but it can still be used in visual, especially for the observation of galaxies, nebulae or star clusters. The Newton Quattro are the best tools for observing or photographing weak objects, with very low costs. They are born for deep-sky photography but they also lend themselves very well as a tool for observations of both weak and planetary objects. Compact, but heavy and robust, it requires use with EQ6-R or AZEQ6 and higher range frames.
