How to rebuild a 10 Telescope

Webb Telescope is designed to capture high-resolution images of distant planets, solar systems and other objects. The launch of the telescope into space is an exciting event. Once the telescope has made contact with space, its components will begin to unravel.

This easy design and written/pictorial instructions will enable you to construct your own 10″ Newtonian Dobsonian Telescope at the lowest cost! Making this project fun for both ages!

Mirrors

Reflector telescopes need primary and secondary mirrors that are collimated to create sharp images. To achieve this the optical axes of the telescopes need to be aligned with their center for maximum performance. While this procedure can be complex for larger telescopes but for smaller ones, it is simple and only requires some patience and dexterity to accomplish.

Then, look for the optical components that you can see through an empty drawtube. For example, the primary mirror and spider reflections. Be sure to pay attention to their centers – this observation method is referred to as Ronchigraming. It can be performed manually or with software such as FigureXP.

Adjust the screws that tilt the primary and spider until the secondary’s center spot appears to be centered in the sight tube. Repeat this procedure until both primary and secondary sweet spots are located at their respective centers in view. Also, ensure that both axes of the focuser and spider are aligned in the sight tube (though this step may often be removed depending on how precisely you calculated earlier), which is known as collimation.

Tube

The ES 10″ stands apart from the majority of Dobsonian telescopes because of its tube made from birch plywood instead aluminum for a variety of reasons. it is easy to work with, has excellent torsional rigidity and strength and costs significantly less. Additionally, its octagonal rings serve as baffles that prevent sunlight from entering the primary mirror. They are secured using epoxy plugs that are inserted through holes in the wood instead of being directly screwed to it. This reduces potential damage while eliminating exterior fasteners that detract from aesthetics as well as potentially snag clothing while transporting.

The tube is mounted on a sturdy Dobsonian Base that is both user-friendly and extremely solid. It utilizes large diameter altitude bearings as well as Teflon azimuth-bearings to allow for smooth up/down and left/right motions. Additionally, it comes with tie-down rings that connect beanbag counterweights in order to stop the telescope from tilting.

The Ocular Tube Assembly is equipped with a two-speed” Crayford focuser to facilitate easy focusing and an 1.25″ to 2″ adapter so that a range of accessories and oculars may be used with this set.

Base

This classic Dobsonian 10″ telescope is an excellent entry-level telescope for stargazing. It’s also affordable with its affordable design. The mirror is well designed and is mounted on a sturdy base that is easily put together. Everything you require to begin exploring the universe is included!

The base is designed in the style of a lazy Susan that is equipped with sealed bearings to enable smooth azimuth and altitude movement as well as the ring of plastic that runs through its lower portion, featuring single degree increments on its angular markings; this allows you to zero out your telescope by first aiming it towards Polaris before sliding its ring until its reference mark aligns with the coordinates on its base.

This makes moving and aligning its mirror simple with the included Laser Collimator, as well as using its fan to bring the temperature of the mirror to ambient faster and to adjust its balance when switching eyepieces. A battery-operated fan also assists. Plus, an included removable counterweight set lets you adjust the balance prior to changing the eyepieces.

The telescope comes with steel carrying handles that are conveniently placed around the center of gravity. This makes it much easier to carry and move. However, this heavy tube assembly will require transportation. Included are a 1.25″ Moon Filter, 2″ 30mm super view eyepiece, as well as a 9mm Plossl Eyepiece, which provides you with an excellent starting magnification. This will allow you to view planets or deep-sky objects that require further magnification.

Accessories

You should consider a few things when you are considering making your telescope. Most people build their own telescopes to save money and gain experience (which can be beneficial in gaining knowledge about the science of astronomy) or to test themselves. Whatever your motives for creating one yourself, the basics tools such as table saw, band saw or drill press will be required for most amateur telescope makers.

Orion ReBuild-a-Scope 10″ Classic Dobsonian Telescope comes with all the necessary accessories including an 8×50 finder scope with image correction capability and two eyepieces, as well as a 3x Barlow lens, plus laser collimator for fine-tuning optical system The optical system is fine-tuned withStrong Neodymium Magnets to stabilize the image and Moon filter to minimize surface glare and reveal increased depth of moon’s surface.

This 10″ Dobsonian features an exquisite parabolic mirror that is housed in an optical tube made of enameled steel and resting on an innovative Dobsonnian base that is fitted with sealed ball bearings to enable smooth altitude adjustment and rocker box control. Its large aperture allows you to see celestial objects like Saturn’s rings, Saturn’s striations and Mars’ ice caps. It even includes an adapter that can be used with multiple eyepieces.
