The Explore FirstLight 254mm f/5 Alt-Az Dobsonian Telescope gives users high performance at a reasonable price.

With a large parabolic primary and smaller secondary mirror made from low-expansion glass to eliminate distortion across the entire field of view, this scope allows for sharp resolution of star clusters and nebulae that smaller apertures cannot.

Its f/5 focal ratio and hexagonal rack-and-pinion focuser make this a perfect choice for imaging as well. The fast focal ratio helps devices capture images in less time than slower scopes and gives it the ability to achieve sharp focusing with strength to handle large imaging rigs and eyepieces.

No telescope type has changed the hobby quite as much as the Dobsonian. Before the introduction of the Dobsonian by John Dobson, the vast majority of amateur telescopes consisted of small telescopes with primitive mechanics - barely enough to see the polar caps of Mars or the rings of Saturn. Larger telescopes, such as the Schmidt-Cassegrain were reserved for the wealthy. The ingenious combination of simple yet effective mechanisms with the greatest possible opening gives the Dobsonian telescope a unique triumphant march around the world. Nowhere do you get as much light for your money like a good Dobson.

Now, Explore Scientific has come up with the ultimate universal design. This Dobsonian can be converted into a Newtonian telescope. If you ever wanted to take pictures, simply unscrew the bearings from the tube and place the scope on an EQ mount with the included Vixen style dovetail plate.

The unrivaled stiffness of the included 2.5" HEX focuser with helical gearing makes focusing easy and allows the use of both 1.25" and 2" eyepieces. Including the 2.5" Hex focuser is a quantum leap for this price class of telescope.

A Red Dot viewfinder as well as a 25mm SPL eyepiece are included with the device. If you want to transport the telescope as compactly as possible, the new 10" FirstLight Dobsonian / Newtonian is easy.

The Rockerbox can be dismantled with a few tools, because the parts are assembled with metal quick connectors. Thus, a bulky rocker box quickly becomes a handy flat package of boards. The ideal workhorse for the deep sky observers. Details on planets and deep sky objects will be visible even for inexperienced observers. Bright star clusters are resolved to the core, and the sight of the terminator on the moon is an unforgettable experience.

The scope is ready for use with our optional coma corrector.

10 inch Solid Tube Dob Review

I really enjoy the solid tube being constructed of metal. While the tube is probably heavier than a fiberglass or resin tube, the metal is sturdy and stiff. Similarly, the metal tube allows you to add weight to portions of the tube for fine balancing via the use of magnets (or magnets attached to a weight bag). I like that this particular scope comes with OTA rings, which makes balancing the OTA in the rocker box assembly quite easy. They also provide a good handhold for carrying the OTA. The rocker box base assembly is of good quality as well. I would have preferred that the teflon pads have that separate the rocker box base from the rotating platform be placed directly over the feet instead of between the feet on the circumference of the rocker base. There can be a issue of "pinch" as the material sags under weight and over time, which will impede the rotation of the box across the azimuth.
