Newtonian Reflector Design. Dobsonian telescopes are exclusively Newtonian reflectors. It is also another reason why they are the best telescopes for the money. The Newtonian reflector is using mirrors to produce the image in the eyepiece. The first telescope invented was refractor using lenses, and there was the problem to scale it up in size. The Dobsonian telescopes are the same reflector-type scopes as Newtonians are. A Dobsonian telescope has a primary parabolic mirror and a flat secondary mirror that are both located in a tube with open ends. On the side of the tube, an eyepiece is attached to help you see things comfortably. 27/01/2017 · Click on this Amazon link to check prices for Dobsonian telescopes. amzn.to/2jAP2ip We receive a small referral fee as we are an Amazon affiliate if y. 03/02/2017 · In this video, we explore the differences between refracting and reflecting telescopes. ~~~ Support me on Patreon! /randydobson ~~~.

Refractors are more rugged, and more easily adapted to photography. Less. Dobsonian telescopes are great because you get a lot of aperture for your money. A refractor telescope of similar size and image quality would be much more expensive. Of all the telescopes listed here, the Zhumell Z12 Deluxe Dobsonian has the largest aperture at 12”. The Orion 8974 SkyQuest and the SkyWatcher S11800 also have large apertures.
Dobsonian Telescopes. In the 1960s, John Dobson's simple new telescope design revolutionized the hobby of amateur astronomy and brought "sidewalk astronomy" to the masses. More than half a century later, Dobsonian telescopes are still a favorite among experienced stargazers for providing the hands-down best value-per-dollar on the telescope market. 11/06/2014 · If a person has the money to either buy a Schmidt-Cassegrain Meade LX200 8" ACF, Celestron 9.25" CPC or a truss dobsonian Orion Skyquest XX16g which would you choose?

21/11/2018 · Re: Dobsonian vs Reflector Sorry for the interjection but it is not quite accurate saying the dobsonian is just the mount. It’s a reflector but the dob has a flat secondary mirror with a continuous light path the full length making dobsonian optical tubes ~ twice as long as Newtonian. I am a proud owner of a small Skywatcher 80mm F5 refractor and have been using it for almost a year now. It's a great low budget scope and I love estimating variable stars from the binocular list. However, I am looking for an additional bigger scope, also suitable for visual VS estimation. It is hard to classify the Dobsonian Telescope as a single invention. In the field of amateur telescope making most, if not all, of its design features had been used before.  John Dobson, credited as having invented this design in 1965 points out that "for hundreds of years, wars were fought using cannon on 'Dobsonian' mounts".
