The Orion SkyScanner BL135mm Dobsonian Reflector Telescope Kit - which includes extra must-have items described below - will reveal the Moon's crater-scarred surface and the Orion Nebula's gaseous ghostliness in amazing detail, not to mention hundreds of other celestial gems. The whole family can get in on the action from the very first night out with the SkyScanner BL135mm Dobsonian.

This beginning Dobsonian telescope blows away traditional starter telescopes, both in terms of image brightness and ease of use. It features a big 135mm (5.3") mirror that collects gobs of light, which accounts for those bright images we mentioned. The optical tube glides effortlessly on its sturdy Dobsonian base. It's so easy to operate - you just point the tube and view. There are no complicated gears, counterweights, locking levers, or tripod legs to deal with as there are with many beginner telescopes.

The 2" focuser can accept optional 2" eyepieces or 1.25" eyepieces, two of which are included. The 25mm Kellner eyepiece provides 44x magnification while the 10mm Plossl eyepiece delivers high-power 110x magnification. Keep the one you're not using in the convenient eyepiece rack. These eyepieces are a definite cut above the typical cheapie jobs found in most competing beginner telescopes. And their barrels are threaded to accept optional Orion 1.25" filters.

Zero in on your target with the red dot scope. Also included is a 3x Barlow lens, which triples the magnification of any eyepiece it's used with. It's a great tool for getting in tight on your observing target. And to aid in your viewing of our favorite celestial object - the Moon - we include the Orion MoonMap 260. It shows the locations and names of over 260 features on the Moon such as craters, mountains, valleys, and "seas".

In addition to the accessories noted above, the SkyScanner BL 135mm Dobsonian Reflector Telescope Kit comes with three more must-have items, making it an unbeatable deal for the new astronomer.

Cut the Moon's glare and see more detail on its surface with the Orion 13% Transmission Moon Filter .

This popular accessory reduces glare and boosts contrast so you can enjoy more-detailed views of lunar surface features. It blocks 87% of the Moon's brightness to provide a more comfortable view and reveal subtle details. It's a neutral density filter that will not alter the natural color of the Moon, either.
