This telescope is ideal for backyard astronomy enthusiasts or older children with space on the brain. Simply turn the telescope on, choose the object you want to see on the handheld controller and the computerized GPS mount does the rest. The fully coated achromatic 80mm primary objective lens is maintenance free and ready to use right out of the box. With a short 400mm focal length, this little bundle of power packs a super-fast F/5.0, which means it's the perfect light-gathering instrument for wide-field and deep space astronomy. With this kind of light-gathering power, you will see bright images of anything through either of the two powerful Kellner eyepieces. That makes this telescope ideal for just about any observing application. The iOptron SmartStar-G Alt-Azimuth Mount with GPS, a.k.a. 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. 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 GoToNova computerized control system is by far the most technologically advanced automated tracking system available on the market today. With a database of 50,000 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. There is no need to align the telescope, with GPS, it knows its location. 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.

  • 80mm fully coated achromatic objective lens, 400mm focal length
  • Super Bright f/5.0 F-ratio for outstanding brightness
  • 25mm & 10mm Kellner 1.25" diameter eyepieces
  • 6x26 finding scope included
  • Portable "instant use" mini-tripod and carry bag included

A Beginner's Guide to Astronomy

!9# A Beginner's Guide to Astronomy

[if ]
[endif]

Astronomy is both a science and a hobby and it's a subject that is accessible to almost everyone.   Indeed, humans have gazed at the night sky with a sense of wonder and fascination for millennia and the starry skies have inspired poetry and philosophy as well as science and exploration.  It's a hobby the whole family can enjoy and anyone can join millions of others who enjoy this subject just by stepping outside on a cloudless night and looking up at the sky.

You don't even need a telescope to start enjoying astronomy.  You can pick out major constellations, the moon, and several planets using the naked eye or with a pair of binoculars that you might already possess for other purposes.  However, part of the fun of astronomy is the use of the telescopes and they vary from simple designs that cost less than £100 to complex pieces of equipment that cost thousands.

The best way to start your exploration of the cosmos is to pick an evening when the weather is calm and the sky is clear of clouds.  You can start simply by looking out of your window or by standing in your garden, but the more sky you can see the more scope you have for exploration, so if you can go to anywhere that is open land then so much the better.  Also, being out in the country and away from street lights will reduce the amount of light pollution that so hinders the amateur astronomer.

Take a star chart or a beginner's guide to astronomy book.  You can download and print start charts from many astronomy websites and your local library will probably stock many such books.  Of course you could simply buy your own book and start your astronomy library.  Over time it's likely to grow into quite a collection.

Make sure you're dressed appropriately and that you are warm and comfortable.  Some of the clearest nights for star gazing in Europe for example are during the winter.  The air is much clearer and the visibility is so much better as a consequence.  Give your eyes time to adjust to the darkness and if you do take a torch in order to refer to a book or star chart then use a dim setting so that the light from the touch doesn't spoil your night time vision.  If you're fortunate enough to live in a remote part of the countryside, near a desert or up a mountain then you have a distinct advantage over town dwelling astronomers!

If you're budget does stretch to some equipment then the two basics are; a pair of binoculars and a telescope.  The binoculars can be used for a quick check of an intended target area of the sky before you change the position of your telescope.  Your first telescope might be one made by companies like Celestron, Meade, Skywatcher, or Orion. All these companies are recognized experts in their field and provide a range of telescopes for both amateur astronomers and professional star gazers. 

When you start searching for a suitable telescope you'll probably come across references to refractor telescopes and reflector telescopes.  To learn about the differences between these two types and more information, astronomy guides, and telescope reviews visit the two sites listed below.
