It's a big telescope that goes anywhere. New Light. Bridge truss- dobs from Meade take down and set up quickly. So you can take one of these massive windows on the universe out to your favorite dark sky locations with ease. Light. Bridge dobs give you high quality Meade optics, premium components, and ultra portability - all for about the same price as an ordinary tube dob. So get a Light. Bridge truss- dob. And prepare to cross the universe. Diffraction Limited Optics. The 1. 2. Meade optics consistently outperform telescopes of similar and larger aperture. Consumers know that Meade Optics Inside means that what they see through our telescopes will be views that are detailed, crisp and full of contrast. Meade Optical Coatings Aluminum Coatings. Coatings with magnesium fluoride over coat provides bright images full of detail. No reviews by eKomi at this time. We recommend following products: Eyepieces. Orion SkyQuest XX12g Dobsonian By Steve Ringwood. 28 April 2015 Steve Ringwood. The Orion XX12g ready for action. I have only one gripe with this excellent telescope – its weight. Somewhere in the bowels of the manual. Sky-Watcher SkyLiner 200 Dobsonian Telescope. I bought my 8' Dob in June 2003 from Teleskop Service, a German online dealer. It's a good value for money telescope, but as you might expect, it can be improved. Skywatcher Skyliner 300P FlexTube Dobsonian. Having used these on my GSO Dob, I've grown appreciative of how great they are in comparison with other available solutions. TS GSO 200mm f/5 Newtonian Telescope OTA with Parabolic Mirror & 2' Dual Speed Crayford Focuser. Metal Optical Tube with Primary Mirror Cell The optics of this style of telescope are only as good as their mounting, which is why Meade engineers gave the Light. Bridge primary mirror a top of the line, fully adjustable, high strength but light weight aluminum stress free floating multi- point cell with built in cooling fan. A unique focus tension knob and focus lock design gives complete control over focus. Built- In Primary Mirror Cooling Fan Bring the telescope into thermal equilibrium quickly and efficiently with the battery powered cooling fan. The included battery pack for the fan takes 8 (user supplied) AA batteries and is used to speed the cool down process of the primary mirror, improving image quality. The fan is mounted to the rear of the vented primary mirror cell for fast cool down. Solid OTA Mount. The sturdy laminated finish wooden Dobsonian mount includes premium features such as roller bearings on the azimuth (side to side) axis and large diameter aluminum altitude (vertical axis) bearings with a hand adjustable variable tension brake for smooth and stable movement. Steel RA Roller Bearings. Laminated base with roller bearings on the azimuth axis that make movements smooth and effortless. Lightweight Aluminum Trusses. The open truss design of the Light. Bridge Dobsonians means portability of the telescope is dramatically improved over a solid tube design. Taking only moments to set up and take apart for travel, the extremely rigid truss frame design ensures a no- compromises view through the telescope. Hand driven Dobsonian style telescopes by their nature need good mounts with smooth and stable movement to be enjoyable, and here again the Light. Bridge excels. Advanced Four- Reticle Red Dot Viewfinder. Four reticles and varying brightness controls allow this deluxe finder to adjust to your observing needs. Meade QX Wide Angle 2. Orion Sky. Quest XX1. Dobsonian – Astronomy Now. The Orion XX1. 2g ready for action. All images: Steve Ringwood. John Dobson. Seizing the chance to find out how far Dobson. It comes supplied with a 2. The latter assists in setting up the red dot . It went together easily, probably taking about an hour. I was very impressed at how rigid the wood- based mount became when all of the locking threads were tightened. The same goes for the OTA; its two rolled steel cylinders (. Designed to be easily disassembled, it is portable and . This is just aching to be lost on a dark night. The large truss- tube bearings are guided neatly into the base. With the tube installed, the whole assembly has a turning circle of just under two metres. With adjustable tension in both axes, motion of the telescope is smooth, but goes firmly nowhere when unhanded. The primary mirror has a cover protection from the elements when not in use, yet the secondary mirror has no dust cap. I always find this common lapse totally bizarre, since its much smaller collecting area is (relatively speaking) far more valuable. A visit to the Moon. The GOTO system is of the eminently respectable Syn. Scan AZ type, with set- up modes affording auto- tracking and GOTO. On my first clear night, a short start- up session quizzed me on my co- ordinates and local time, after which I opted for the . Absurdly, GOTO systems often have difficulty finding the Moon, perhaps because of its rapid motion relative to the celestial sphere. Yet the Orion XX1. Very impressive. A gibbous Moon offers a deeply coruscated terminator full of craggy detail. Moving to the 1. 2. Its floor and terraces were bathed by exquisitely angled sunlight and the observed resolution demanded a deep dive into the crater. The tightly configured optical system was yielding no scatter or flare that might impinge contrast. The night being superb, the detail provided by the 8mm suggested more might be had, so I replaced it with a 3. The telescope dealt with this demand with alacrity. The slumped material of the gentle inner crumbling slopes was sharply delineated, as were the much steeper rugged cliffs of the outer parapets. I have never enjoyed Copernicus in such high precision. Thank you, Orion. Making full use of the GOTO and slew functions, there was but a purr from the alt- az motors, a welcome change from the brash rattle of some drive systems. One minor annoyance was the otherwise excellent Crayford- style focuser, whose large tactile focus knobs are so positioned as to leave insufficient room for fingers to pass between them and the main tube. Clusters and ice giants. As further nights offered themselves, late autumn sessions gave prequel to winter. High in the east, the Pleiades offered a suitably starry field for the . Transfixed against a very dark field, the lesser stars were so stunningly lifted out of the gloom by the telescope that the familiar . My corrector lens easily brought these peripheral sluggards into line. Autumn, however, brought a dearth of available planets with only distant Uranus and Neptune saving the sanity of planetary observers. The opposition of Uranus provided a unique opportunity for the XX1. Pushing my luck to a 5mm (3. Thwarted, but undaunted, I progressed to Neptune. Although a fair stride eastwards, the motors gently ushered the tube to just the right place; impressive, despite my almost cursory placement of the Dobsonian on level ground. Having moments before observed its . It revealed a relatively diminutive disc with its beautiful turquoise tint. The Orion Sky. Quest XX1. GOTO system of the Syn. Scan AZ type with a database of 4. I have only one gripe with this excellent telescope . Somewhere in the bowels of the manual, it claims that the primary components should be just about . The base weighs 4. I will not claim to be fit, but nor am I infirm. I could lift the assembled base by its handles and stagger ungainly perhaps ten paces before needing a rest stop. I cannot let the pun lie, that here there is another meaning for a truss telescope. I took to using a tarpaulin as a sledge that I leisurely hauled into position for each observing session. I would therefore consider it at the limit of being portable once assembled. Of course, countering that, it is exceedingly stable. I never experienced any vibration or shaking during use . Those considering this telescope may need to look at a Dobo- trolley to help out. This is an optically fine telescope, companioned with a very robust mount. I thoroughly enjoyed using its very able GOTO system, which never failed. I shall remember this telescope most for two wonderful observations; gazing into the maw of Copernicus, and cleaving the double star components of epsilon Lyrae so cleanly that they looked like a small open cluster. Orion Sky. Quest XX1. Dobsonian. Aperture: 3. Focal length: 1,5. F- ratio: f/4. 9. Focuser: Dual- speed two- inch Crayford (1. Supplied eyepieces: 2. Deepview, 1. 2. 5mm illuminated reticle Pl.
