Having enjoyed using Sky-Watcher's Quattro telescopes in the past, we were intrigued by the latest model to join the family, the comparatively diminutive Quattro 150P. As the name suggests, it is an f/4 telescope with a 150mm primary mirror. It includes a corrector that takes the telescope down to a speedy f/3.45.
Quattro telescopes are designed to be used as astrographs, that is, paired with a camera; so the 150P doesn't come with eyepieces. However, optics that make a good astrograph also produce good visuals, and with Jupiter nearing opposition we tried the Quattro with a couple of our own eyepieces, using the supplied 2-inch extension tube. Our 4.5mm lens gave a pleasing 133× magnification
