The bracket is held in place in the mounting shoe by a single large hand-tighten knob that maintains the finder’s collimation, even if the finder is removed between observing sessions. The 8 x 50mm finderscope mounts in a quick release bracket that slips into a pre-installed metal mounting shoe nearer the focuser. This little telescope will show many objects in direct vision for easy location. Powerful 8x50 finderscope, multicoated objective lens. Physical Copies of the manual will not be given.

The absense of Roller Ball Bearings in other branded Dobsonian Telescopes makes it very difficult to move the telescope on the wooden base. This negates the wobbly effect / air turbulance caused due to variations in temperature.Īzimuth Roller Bearings provided at the bottom of the Dobsonian base allows super fine horizontal tracking of celestial objects. Ī Cooling Fan that quickly equalises the temperature of the mirror with surrounding air. The new Altitude Metal Ball Bearings and Clutch System provides smooth vertical motion of the optical tube. GSO Professional Dobs come with Tube Balancing System that allows you to perfectly balance the tube when you add an additional DSLR Camera to the telescope GSO's CNC Machined Crayford focuser comes with a 2" 'DUAL SPEED' 1:10 Micro Focusing Capability. Ĭomes with a large 8x50 Multi-Coated Achromatic Finderscope GSO Professional Dobs come with a 2" Wide Angle Super Plossl eyepiece for Wide Angle / Deep Space Observation. GSO makes the World's Finest Astronomical Mirrors with surface accuracy of 1/12 wave. GSO Dobsonian Telescope with an ADVANCE ROCKER BASEĢ" Crayford focuser - 1:10 micro - reduction from 2" to 1.25"ģ0 mm 2" Wide Angle ERFLE with 70° field for good overfiewĮyepiece and Accessory Tray for Eyepiecesĭust Cap Why chose a GSO Dobsonian Telescope over other brands ? The deluxe model comes with 2" Micro 10:1 Crayford style focuser and 1.25" adapter. Set-up is as easy as you can imagine very simple assembly with the rocker box and put it on the ground, insert the telescope tube and put the springs in position and you're ready to go to navigates through the night sky by simply moving the tube up or down, or side to side, by hand.Īll GSO dobsonian use optical quality BK7 glass, cooling fans built into the rear cell to decrease cooling times, also all dobs use a roller bearing on the azimuth surface providing dozens of support points for smooth swivel motion. AA battery pack for fans not included.The GSO Dobsonian line is particular model serves a very clear purpose, to offer a large aperture and an excellent image quality at reasonable cost. Includes: Two-Speed 2-inch Rack & Pinion Focuser with 1.25-inch Adapter LED Red Dot Finder, Collimation Assist Tool Flexible Light Weight Light Baffle Two Primary Mirror Fans Instructions. Easy-to-adjust collimation mechanisms for primary and secondary mirrors require no additional tools and only one person is a unique feature of this design. Oversize altitude (16.5-inch) and azimuth (13-inch) bearings allow for smooth operation. Many star clusters are resolved to the core, spiral structure in distant galaxies is visible, and the complex matrix of bright and dark nebulae are an unforgettable experience. Details on planets and deep sky objects will be visible even for inexperienced observers. A 254mm aperture mirror collects more than 1,500 times as much light as the naked eye. The combination of large altitude bearings with optimized metal structural design allows fine and smooth adjustment, even at higher magnifications.The ideal workhorse for the deep sky observers. The entire structure has been optimized for maximum stiffness with minimal weight. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in very small cars. The ingenious combination of simple yet effective mechanisms with big-aperture Newtonian optics gives the Dobsonian Telescope worldwide popularity, and this telescope design typically offers the largest aperture per dollar of any telescope type. Large commercial telescopes could certainly do the job but were relatively expensive. Before the popularization of John Dobson’s altazimuth mount design with low center of gravity combined with a Newtonian optical assembly, the vast majority of amateur telescopes consisted of small telescopes with small mounts - which made them difficult to use for serious deep sky observations by beginners. No telescope type has changed the hobby quite as much as the Dobsonian Telescope. All updates have been performed on this telescope. DSLR and Mirrorless Settings for Astrophotography
