EXPLORE SCIENTIFIC - 16 INCH TRUSS TUBE DOBSONIAN TELESCOPE - GENERATION II ... Last updated on 20 … The combination of high altitude bearings with optimized aluminum structures allows fine adjustment flows at high magnifications. The mirror overcomes frequently occurring dew fogging and cleanups without damage and guarantees a long service life. The ideal workhorse for the deep sky observers, the Explore Scientific 20-inch f/3.6 Truss-Tube Dobsonian is our largest aperture telescope. Delivery timeframe: Built to order exclusively - Please contact us prior to order to confirm timeframe, shipping cost and other details. This experience is always a real treat, as the views through this giant “Dob” are incredible. The 6 supporting feet underneath the rocker box offers perfect stability and guarantees smooth tracking in azimuth. All connections of the tube structure were made in the TIG welding process and no rivets and screws were used. Includes 2.5" HEX focuser with helical gearing and 10:1 reduction; LED Red Dot Finder, collimation assist tool; soft light baffle and two radial main mirror fans for fast temperature equilibrium. A laser engraved center mark of the main mirror allows easy adjustment. The entire structure has been optimized for maximum stiffness with minimal weight. Every main mirror is delivered with an individual optical test certificate, which guarantees the highest capacity. Before the introduction of the Dobsonian by John Dobson, the vast majority of amateur telescopes consisted of small telescopes with primitive mechanics - barely enough to see the polar caps of Mars or the rings of Saturn. The optical surface has a high-quality aluminum coating with 94% reflectivity and an extremely resistant quartz protection layer. 20 Inch Dobsonian Telescope Looking Through a 20 Inch Dobsonian Telescope! A photo of me looking through a 20″ Dobsonian Telescope. The 500mm mirror collects 5100 times more light than the naked eye. Four smaller fans are installed in the side of the mirror box as well as a large fan installed under the main mirror. Limited Warranty is one year, which converts to the Explore STAR Transferrable Product Warranty when product is registered within 60 days of purchase. The ideal workhorse for the deep sky observers, the Explore Scientific 20-inch f/3.6 Truss-Tube Dobsonian is our largest aperture telescope. This has made it possible for us to produce this 20" light weight Dobsonian so unbelievably stiff in spite of the low weight - a noticeably good quality which is begging you to take one home. Explore Scientific - Generation II - 20-inch Truss Tube Dobsonian Telescope - DOB2036-00 For a limited time only, receive the following FREE GIFT with the purchase of this Telescope: Explore Scientific Astro R-Lite Red Flashlight Retail Value: $19.99 The ideal workhorse for the deep sky observers, the Explore Scientific 20-inch f/3.6 Truss-Tube Dobsonian is our largest aperture telescope. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in small cars. This allows an even quicker adaptation to the ambient temperature and reduces the tube seeing (boundary layer removal). The production of almost all mechanical components is carried out by our partners in Hungary and the final assembly of the optics and subsequent quality control takes place in Rhede, Germany. Every main mirror is delivered with an individual optical test certificate, which guarantees the highest capacity. The mirror overcomes frequently occurring dew fogging and cleanups without damage and guarantees a long service life. Details on planets and deep sky objects will be visible even for inexperienced observers. Explore Scientific - Generation II - 20-inch Truss Tube Dobsonian Telescope - DOB2036-00 Explore Scientific (Please note: This is a special order item with an estimated delivery time of 90 days.) The scope is ready for the use with our optional coma corrector. Details on planets and deep sky objects will be visible even for inexperienced observers. Description A second 40° displaced installed mounting plate with a viewfinder shoe allows the rotation of the tube top in combination for a favorable position of the viewfinder tube or the mounting of an additional TELRAD viewfinder. The lateral altitude wheels can now be stowed comfortably in the foam layers of the mirror box. The Explore Scientific Ultra Light 20 inch Dobsonian is the largest of Explore Scientific's Dobsonians - offering enormous light gathering power in a comparatively portable package. The fast 20" f3.6 main mirror as well as the large 120mm secondary mirror are made of high quality quartz material, so the cooling time is reduced to a minimum and this Dobsonian is quickly ready for use. A complete redesign of this Dobsonian was necessary to ensure the significantly increased requirements to stiffness and load bearing capacity of the optical components. A laser engraved center mark of the main mirror allows easy adjustment. No telescope type has changed the hobby quite as much as the Dobsonian. The 500mm mirror collects 5100 times more light than the naked eye. Sky Watcher Classic 200 Dobsonian 8-inch Aperature Telescope – Solid-Tube – Simple, Traditional Design – Easy to Use, Perfect for Beginners, White (S11610) 4.0 out of 5 stars 109. A complete redesign of this Dobsonian was necessary to ensure the significantly increased requirements to stiffness and load bearing capacity of the optical components. A member of my Local Astronomy Club in Niagara (RASC – Niagara Centre) owns a massive 20 Inch Dobsonian Telescope that he will often bring out to our Observatory Site in the summer. All connections of the tube structure were made in the TIG welding process and no rivets and screws were used. Bright star clusters are resolved to the core, and the sight of the terminator on the moon is an unforgettable experience. A Million Dollar View.
