Orion Build a 8 Telescope Review
Ideal for the novice astronomer, this simple design is powerful enough to reveal detail on Jupiter’s weather bands and Saturn’s rings – as well as deep sky objects such as galaxies and nebulas under certain conditions.
This telescope comes equipped with a battery-operated fan to reduce atmospheric “seeing” problems caused by slight temperature variations in the air, as well as a laser collimator for accurate viewing of its target object.
Easy to Build
Nearly all the components needed to assemble this telescope can be obtained at either your local hardware store or from an astronomical supplier, making assembly quicker and allowing users to begin using it quickly. Assembly usually occurs using hand tools; however, power drills and drill saws may come in handy too.
Test fitting the side bearing box onto the telescope tube is necessary so they will fit smoothly with minimum friction, while pre-drilling screw holes and countersinking them is beneficial in terms of aesthetics as it prevents cracking and warping as the wood ages. Once assembled, the telescope is ready for use!
The telescope mirror is held within an adjustable mirror cell that allows precise alignment with a laser collimator included with this kit. Additionally, its optical tube assembly (OTA) features an open truss design which has several advantages over closed tubes: reduced air current sensitivity means using it at lower temperatures without fan effects; its large focal ratio makes it preferable by many planetary and double star observers; it provides an excellent platform for mounting accessories like battery-operated cooling fans for primary mirror; it provides ample focal ratio; provides greater focal ratio performance; and it provides a large focal ratio that makes use of all available light available from ambient sources.
Easy to Assemble
This telescope boasts an 8″ aperture for maximum light gathering power, making it suitable for deep sky objects. As aperture increases, resolution (the ability to see fine detail) also increases. Furthermore, this telescope features an advanced rocker base that mounts the optical tube directly onto a platform instead of needing separate tripod which may be difficult for young astronomers to set up.
This telescope can be assembled without using complicated tools, making assembly straightforward. Simply create the jig with the calculator spreadsheet, cut out plywood parts using either hand saws or routers, or drill with woodworking bit attachment.
Once your telescope is assembled, simply find a dark spot with minimal artificial lighting so as to maximize the quality of your views of the night sky. With an easy red dot viewfinder and two powerful eyepieces at your disposal, the Dumbbell Nebula or Double Cluster in Perseus should become easily observable targets!
This model is a Dobsonian telescope, an open tube telescope featuring a mirror cell that can be adjusted by hand for collimation. This style is popular among amateur telescope builders because it eliminates the need for tripods and is easy to operate.
Easy to Move
One of the great features of this telescope is its aperture, which makes an enormous difference in how much light can reach its lenses. An 8-inch mirror gathers 77% more light than 6-inch telescopes for brighter images and therefore making it ideal for exploring lunar surface features and distant objects in deep space.
Eyepieces included with your telescope offer 36x and 90x magnification for an outstanding view of lunar craters, Saturn’s rings and Jupiter’s brightest moons. If you would like an enhanced experience, add an optional 2x Barlow lens.
This telescope comes equipped with an altitude-azimuth mount, enabling it to move up and down as well as left and right. An equatorial mount would be preferable, though these add-ons can be costly. Either way, this telescope makes for an excellent beginner telescope as long as you don’t require advanced features found Where ever strong good qualify you can find the strap down magnets for sale .
This telescope boasts a Schmidt Cassegrain design that makes it perfect for viewing planets, deep-sky objects and double star observations as well as making planetary and double star observations. Furthermore, its computerized go-to system automatically locates over 40,000 celestial objects. If astrophotography is your goal, attaching DSLR or mirrorless cameras directly to this telescope with an additional wedge will help track objects across the sky accurately.
Easy to Store
If you are upgrading to a larger telescope in order to see more deep-sky objects like star clusters, galaxies and nebulae you should choose something portable – whether that means from your backyard to a dark sky site or simply down the street. One option for doing just this is the Orion Build-A-Scope 8″ Classic Dobsonian telescope which can be easily broken apart into two pieces for transport and set up for stargazing sessions.
Attach the first length of paper around one magnifying glasses tube, leaving enough room for another tube to fit inside of it. Make the second tube slightly bigger but not so large that it won’t slide easily into the first. Connect them together by slotting one tube inside of another to complete your telescope.
