Quattro Imaging Newtonian Telescopes
Fast, like, REALLY FAST
The Quattro Imaging Newtonian is one of the most affordable telescopes with a f/4 focal ratio. This astrograph is capable of producing an exposure 6x faster than the average 8” f/10 Schmidt Cassegrain telescope! Even pricey refractors have trouble reaching a focal ratio this fast. Using a faster optical tube will shorten the exposure time on your camera, giving you more time to photograph nebulae, clusters and other deep sky objects.
