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) • f / 4 brightness for astrophotography (strong stand required), as well as for advanced visual observations • efficiency of mirrored surfaces 94% of the main • 3-inch cut with 2-inch and 1.25-inch reductions with a 10: 1 micro-processor • Optical finder 8x50 fixing to the tube • 2 "/ 2" eyepiece adapter 35 mm with clamping ring • tube clamps and dovetail mounting rail 75 mm wide (Losmandy) • Optical system: Newton reflector • Diameter of the lens: 305 mm • Focal length: 1200 mm • light: f / 4 • Switching capacity: 0.46 " • Stell ratio: 15.5 magnitudes • Maximum useful magnification: 600x • Length: 1117 mm • Weight: 21.6 kg (including lift, finder, clamps) Moon the planet star clusters nebulae astrophotography 2 years
