10″ f/5.0 Closed Tube Dobsonian Telescope

As expected from a Dobsonian Telescope, our 10-inch closed tube Aperture Telescope collects a lot of light from the night sky. It collects 1.5 times the light as compared to an 8-inch telescope. The telescope is still quite portable and can be carried anywhere easily.

The 10-inch telescope is highly recommended as a first step up for a beginner or amateur astronomer. A 10-inch telescope will take your hobby of astronomy to greater heights and delight you with wonderful views of the night sky wonders.

Our 10-inch Dobsonian Telescope can be operated easily by children. The movements of the telescope are so intuitive that children do not think twice before starting to use it. Especially children are able to point the telescope at any object in the sky without any prior experience. The smooth and controlled motion of Aperture Telescopes, make it “Easy-To-Use”. No backlash, no runaway, just easy movements in both axes.

The 10-inch Aperture Telescope has a traditional closed tube design. The design is very effective in cutting off stray light from all directions, so the views have good contrast without any light leaking from any direction into the eyepiece. The 10-inch aperture provides enough resolution to show fine details on the Solar System objects, viz. Moon, Saturn, Jupiter, Mars and other planets.

The main feature of a Dobsonian telescope is good light collection. The 10-inch telescope can show you numerous deep sky objects from dark skies. Since the telescope is portable, you can carry it to remote areas for deep sky observations. The fast f/5 focal ratio renders the deep sky objects relatively brighter. You can achieve sharp aberration free focus with the parabolised optics. Additionally with the use of Crayford focuser provided, you can achieve perfect focus. Crayford focusers use a toothless friction system that allows for super-fine precision focusing without backlash. The focuser accepts eyepieces of 1.25" as well as 2" standard.

Our Dobsonians feature Teflon bearings and move smoothly in both axes. The altazimuth mount is rock solid. We use marine plywood instead of popular MDF board in imported telescopes. The marine plywood covered with laminate becomes weatherproof, for a long duration, as compared to MDF which warps with dew and moisture, and becomes unusable over a short time.

The telescope comes with a Plössl eyepiece 25mm (50x), 1.25" standard. We provide the best zero power finder - Telrad, to locate objects in the sky easily.
