Unplug your electronic devices, step outside, and become immersed in the wonders of the universe. Although we love computerized telescopes, using a star chart to find objects by hand can be far more fulfilling and will improve your knowledge of the night sky. All Flextube Dobsonians come with a slew of accessories, including: two 1.25-inch eyepieces, a 1.25-inch eyepiece adapter, a 2-inch eyepiece adapter, dust caps and a 8x50 finderscope.Īt Sky-Watcher, we stay true to the traditional John Dobson design, while offering a fresh look for the 21st century. Once locked on an object, the telescope can support both 1.25-inch eyepieces as well as the heavier 2-inch eyepieces, allowing you to use virtually any eyepiece on the market. The base uses Teflon bearings for smooth, easy Azimuth slewing and a patented tension control handle to lock the telescope in place. Before the introduction of the Dobsonian by John Dobson, the vast majority of amateur. Supporting the Flextube Dobsonian is more than just a simple rocker box. No telescope type has changed the hobby quite as much as the Dobsonian. With a 12-inch aperture, the Flextube 300P Dobsonian collects 1840 times more light than the human eye! This simple yet effective design is perfect for visual observation of faint objects, such as nebulae, star clusters, and galaxies. The optical tube uses a parabolic primary mirror, constructed of borosilicate, then polished and coated with our proprietary Radiant Aluminum Quartz (RAQ), producing a remarkable 94% reflectivity. The Flextube Dobsonian innovates on that original design, offering users the ability to collapse the optical tube using a proprietary truss-tube system while retaining its collimation. This type of glass, typically used in laboratories, can withstand thermal. Dobson, who literally wrote the book on how and why to make amateur telescopes, encouraged other astronomers to assemble their own telescopes and taught workshops on telescope making. The Saxon 12 Dobsonian Telescope is fitted with a primary mirror made of Pyrex Glass. These were often made with found materials, heavy cardboard tubes, recycled porthole glass, and plywood mounts. Dobson was well known for constructing large aperture reflecting telescopes capable of deep sky viewing, using low cost materials. Meade 12' LightBridge Plus Truss Tube Newtonian Telescope. The name '˜Dobsonian' comes from the telescope's inventor, John Dobson, a Vedanta monk who popularized sidewalk astronomy, and dedicated his life to astronomy outreach. This large-aperture Dobsonian boasts a 1524mm focal length and an impressive light-gathering ability, resulting in sharp, clear images of planets and deep-space objects alike. ![]() Often referred to as '˜light buckets', Dobsonians provide users with the highest possible aperture for their money when compared to telescopes of a similar size, such as Schmidt-Cassegrains or refractors.ĭeveloped in the 1970s, the Dobsonian-style telescope is an inexpensive solution for bright, detailed visual observing using a simple design. For decades, the Dobsonian stood as a DIY staple of amateur astronomy, usually constructed with two mirrors, a tube and a base.
