Webb Telescope is designed to capture high resolution images of distant solar systems, planets and other objects. Its launch into space is a thrilling moment. When the telescope has made contact with space, its parts will start to unfold.
This easy design and written/pictorial instructions will help you build your own 10″ Newtonian Dobsonian Telescope at an affordable cost! Making this project fun for both ages!
Reflector telescopes require collimated primary and secondary mirrors for sharp images. To achieve this, the optical axes have to be aligned at their centers to ensure maximum performance. While this can be complex for larger telescopes, for smaller ones it is simple and only requires some patience and dexterity.
Then, you should look through your focuser with your telescope pointed towards the sky or the ceiling (being careful not to touch any reflective components) Then, look for all optical components observed through a drawtube empty such as the primary mirror inside its holder, as well as spider reflections reflected therein. Pay attention to their centers. This observation technique is referred to as Ronchigraming. It can be accomplished by hand or using software such as FigureXP.
Adjust the screws to tilt the primary and spider so that the secondary’s sweet spot is aligned within the tube. Repeat this process until both sweet spots appear in their respective positions in view. This is referred to as collimation.
The ES 10″ stands apart from other Dobsonian telescopes with its tube made of birch plywood rather than aluminum for several reasons: it is a breeze to work with, has excellent torsional rigidity and strength and is significantly less expensive. Additionally, its octagonal rings serve as baffles to block any light that is not directed towards the primary mirror and are secured using epoxy plugs that are inserted through holes in the wood instead of being screwed directly into it. This minimizes the possibility of damage, while removing earth magnets fasteners that can detract from aesthetics and could snag clothing while transporting.
The tube is mounted on a stable Dobsonian Base that is both user-friendly and extremely sturdy. It utilizes large diameter altitude bearings and Teflon azimuth-bearings that allow for smooth up/down, as well as left/right motions. Additionally, it comes with tie-down rings that connect beanbag counterweights to prevent the telescope from tilting.
The Ocular Tube assembly comes with two” Crayford Focuser with two speeds that make focusing easy. It also includes a 1.25″ – 2″ adapter, allowing accessories and oculars are able to be used.
An 10″ telescope can make an excellent telescope for stargazing at a basic level, and this classic Dobsonian design is suitable for budgets of any size. The parabolic mirror is expertly constructed and rests on a sturdy base that can be easily assembled. Everything you need to start exploring space is also included!
The base is designed in the form of the lazy Susan that is equipped with sealed bearings to enable smooth movement of azimuth and altitude as well as the ring of plastic that runs through its lower part, with single degree increments on its angular markings. it allows you to reduce the size of your telescope by first aiming it toward Polaris before sliding its ring until its reference mark aligns with a coordinate that is on its base.
This makes moving and aligning its mirror a breeze using the included Laser Collimator, as well as using its fan to quickly bring the mirror back to its normal temperature faster and adjust its balance when switching eyepieces. A battery-powered blower can also help. In addition, a built-in counterweight set lets you determine the balance prior to changing the eyepieces.
The telescope comes with steel carrying handles that are located around the center of gravity. This makes it much easier to carry and move. However this tube assembly is heavy and will require transportation. A 1.25″ Moon filter, together with a 2″ 30mm Super View eyepiece and a 9mm Plossl eyepiece are included for starting you off with a high-quality magnification so that you can see the details of planets or deep sky objects that require further magnification.
You should think about a few things when you are considering making your own telescope. Most people build their own telescopes in order to save money, gain experience (which could be helpful in gaining knowledge about the science of astronomy) or to push themselves. Whatever your motives for creating one yourself, basic tools such as table saw band saw, table saw or drill press will likely be required for most amateur telescope makers.
Orion ReBuild-a-Scope 10″ Classic Dobsonian Telescope comes complete with all necessary accessories, such as an 8×50 finder scope that has ability to correct images, two eyepieces and a 3x Barlow lens, as well as laser collimator for fine-tuning the optical system It also comes with Strong Magnets for stabilization and Moon filter to minimize surface glare and reveal increased detail on moon’s surface.
This 10″ Dobsonian has an exquisite parabolic reflector, housed in an enameled steel tube. It is mounted on a Dobsonnian base with sealed ball bearings that allow for smooth altitude adjustments as well as rocker box controls. The large aperture will let you see celestial objects from Jupiter’s equatorial belts, to Saturn’s rings and Mars Ice caps. It is also equipped with an adapter sized 2 inches to 1.25″ to work with multiple eyepieces and accessories!
