Here I will go over the whole process of operation needed to set up this telescope, and the front collimation feature. The Explore Scientific 10 inch dob, while being a truss-style telescope is still a Newtonian reflector type telescope with some basic features that you will find across most telescopes that you should know before considering purchasing this scope. The Explore Scientific Dobsonians are well known for including high-quality accessories with their telescopes that make the ease of use and quality of viewing better. You can mount the altitude bearings at different positions to take into account different eyepiece weights so the telescope does not become unbalanced. In conclusion to this review, I believe that the Explore Scientific 10” truss Dobsonian telescope is one of the best portable scopes released in recent years. The mirror box is where the altitude bearings attach to, as they pivot up and down. The telescope includes mirror cooling fans that are incorporated in the box. Page 1 of 4 - Explore Scientific 16 Truss Review + Mods +Add-ons - posted in Reflectors: Explore Scientific 16 Truss Dobsonian Review Special Note: The primary mirror has been sent to Swayze Optical for testing. The Dobsonian telescope design was created by John Dobson for an affordable way to get big aperture in an easy to use telescope design. Save my name, email, and website in this browser for the next time I comment. The truss poles detach from the upper and lower sections of the telescope easily, leaving only the lower and upper tube assemblies, which themselves are very small. Won’t lig. The upper tube assembly sits on top of the truss poles, and it holds the secondary mirror, finderscope, and focuser of the telescope. Enjoy the heavens with this large, yet portable, Explore Scientific 10" Truss Dobsonian. This means that there is no tube at all. We tested their Generation II 16-inch option, which has been upgraded recently to improve its mechanics. The results are after this post. There has not been a true first light, Just visual inspection and quick collimation testing. Deluxe Red-dot finder. I will discuss the specifications of the scope, what it includes, what makes the truss design different, and how you use truss telescopes. The mirror box is typically very short as it does not do much more than hold the mirror in and collimate the mirror. Edited by davidpitre, 12 June 2016 - 06:53 PM. Explore Scientific is one of the newest telescopes and astronomy equipment manufacturers, and it is taking the US by storm with its high quality and relatively low-cost telescopes and eyepieces. The poles make up the bulk of the telescope’s length but are quite small. The focuser includes a dual-speed know which allows you to focus more finely. Truss poles are the set of eight poles that form a triangular shape (hence the name truss) and make the telescope extremely rigid – perhaps more rigid than a closed tube telescope. A solid tube telescope is where the tube that holds the mirrors was completely solid, typically metal or in some cases wood. *Rankings and ratings are calculated by comparing all telescopes on the same price range, in this case, $600 to $800. The primary mirror is overcoated with Quartz. In my opinion, something like a Telrad finder is much improved, but a red dot finder gets the job done without being extremely heavy. Our Product #: ES10D. As the large, heavy tube is ditched for eight poles, the truss design allows this telescope to be FAR lighter and FAR smaller than its alternatives. A 10-inch dob is on the verge of a “large” Dobsonian, as it will reveal some of the darker objects like faint galaxies under dark skies but may not show them in great detail. How can that be? Next is the mirror box, and it is as the name implies, where the main mirror is located. Our renowned experts have reviewed 100+ telescopes and have made a rank list based on budget and quality. The truss poles attach to the top of the mirror box. Explore Scientific Dobsonians are built on high quality mirrors with smart design features that makes them surprisingly portable. This means that the primary mirror has a diameter of 250mm or 10 inches. The 10” Explore Scientific Truss Tube Dobsonian is an ideal workhorse for deep sky observers. This means that you no longer have to reach to the back of the telescope, risking bumping the telescope and walk back and forth between the eyepiece and mirror box, instead the ES dob includes a tool to collimate the telescope from the eyepiece, so you do not have to reach down to the mirror cell. Solid tube Dobsonians would be much harder to transport, as the rocker box is much larger, and the tube itself is very long. Next, the upper tube assembly is attached to the top of the 4 truss poles, also with thumbscrews. The F/5 focal ratio also does not create as much coma as a faster mirror and because of that, you do not need an expensive coma corrector to remove distracting aberrations. Details on planets and deep sky objects will be visible even for inexperienced observers. Some of the accessories can improve your observing experience greatly, so I will list them here. The ES 10” dob includes a red dot finder.
