This telescope is ideal for backyard astronomy enthusiasts or older children with space on the brain. Simply align the telescope with the North Star, choose the object you want to see on the handheld controller and the computerized mount does the rest. With a large 114mm (4.5 inch) primary mirror and a 500mm focal length, this fast F/4.4 telescope is the perfect large light-gathering instrument for wide-field and deep space astronomy. You can observe fabulous nebulae, galaxies, binary star systems and most of the famed deep-space Messier objects. Of course, with this telescope, you can see outstanding detail when viewing the moon and you can see the Rings of Saturn and the Moons of Jupiter. Did we mention that all you have to do to see a new object is push a button? The iOptron SmartStar-E Alt-Azimuth Mount, aka The Cube, is probably the most functional and flexible unit on the market. Both axis motors are built into a small single unit. In addition, there are no "dead spots" -- so you can point your telescope anywhere above the horizon, whereas, other mounts block the telescope tube at certain points of rotation. This mount comes standard with AC connection, but also accepts 8 AA cell batteries for use at home or in the field (Batteries sold separately). The revolutionary GoToNova computerized control system is by far the most technologically advanced automated tracking system available on the market today. With a database of 5,000 celestial objects, including all of the most famous galaxies, nebulae, star clusters, not to mention the planets, you'll be able to enjoy star gazing with the simple push of a button. The GoToNova Controller is much easier to use than other similar products. The hand controller is more intuitive with menu categories better organized. It also has a larger LCD screen with more lines of content compared with the competition. With the easy-to-use hand controller you can easily set up your telescope and select where you want to go.
