A complete optical tube with a 305 mm F / 4 mirror (12 inches, focal length 1200 mm), with a monorail (modified Crayford extractor) 3 "/ 2" / 1.25 "with a 10: 1 microscope and a very good finder 8x50, designed for advanced astrophotography and highly advanced visual observations, both solar system objects, as well as star clusters, nebulae and galaxies, has a very bright parabolic mirror, relatively small size and 21.6 kg weight with clamps, which makes this telescope very fast and efficient astrograph.
To get a good working comfort we recommend the NEQ6 Sky-Watcher, available separately for this tube. • large glass mirror with diameter 305 mm (12 inches)
