Orion Skyquest XT4.5 Classic Dobsonian Telescope ReviewThe Orion Skyquest XT4.5 Classic Dobsonian Telescope is one of the most compact telescopes in the Dobsonian category and is quite powerful as well. Usually, telescopes of similar power and clarity come in intimidating sizes and prove to be too much for amateur stargazers. However, the Orion Skyquest XT4.5 stands only around three feet tall and is at an ideal height for a child, and an adult amateur can sit comfortably on a chair, and enjoy viewing celestial objects.

Orion Skyquest XT4.5 Classic Dobsonian Telescope LensesOrion Skyquest XT4.5 features top-quality optics with a respectable power, which is more than enough for amateurs, and intermediate stargazers. The 4.5 inches primary mirror with a focal length of f8 is much more powerful compared to a refractor of 60mm and can capture two and half times more of the starlight.

The mirror itself is spherical rather than parabolic, but it does not affect the viewing in any way. This light-gathering power makes it ideal for watching relatively fainter celestial objects in better detail, making it one of the top contenders for telescopes in its price range.

The nearest contender could be the Meade ET60AT, which has a 60mm lens but is left way behind in terms of clarity and size of image compared to the Orion Skyquest XT4.5. You can get great views of galaxies, nebulas, craters of our moon, breathtaking vistas of Jupiter, and rings of Saturn.

Easy to Use and Great Educational Tool

The compact design of the Orion Skyquest XT4.5 makes it quite portable within your premises, even when it is fully assembled. You can just carry it out to your terrace or porch on a starry night, and enjoy the skies. All controls are easily accessible, and maneuvering the device is quite simple, once you have read the instruction booklet, which is quite well written. You do not need technical knowledge for aligning the scope, and the included software proves to be of great help in finding celestial objects.

Once you have assembled the telescope, it is ideal for a child to operate the device because of its low height. It is the best astronomical learning tool you can find in the market today. Even though the Orion Skyquest XT45 does not have an intimidating size, it is much more of a professional device, compared to the huge flimsy models available at many departmental stores.

This telescope is not a toy and is the ideal device to encourage the interest of young minds in the astronomy field. The Orion Skyquest XT4.5 delivers razor-sharp resolution, and you can have hours of educational entertainment with the whole family.

Orion Skyquest XT4.5 can be Easily Assembled

The Orion Skyquest XT4.5 comes in two packages. One carton houses the optical tube, and the other packs the base and other components. However, the whole configuration is quite easy to set up with the help of the instruction manual. The product packs all the tools and hardware required for the assembly, and even an amateur can set up the telescope with proper alignment, within the hour.

Great Value for Money

Orion Skyquest XT4.5 Classic Dobsonian TelescopeAlthough the Orion Skyquest XT4.5 is a highly professional telescope with very good optics, it comes at a relatively low cost when you compare other bulkier telescopes having almost the same power and configuration. In fact, in this price range, there are many models, which might look impressive but prove to be useless junk. The Orion Skyquest XT4.5 has broken the price barrier in a big way and made a professional device accessible to people at a much cheaper price.

For instance, the Meade ETX60AT comes with an electronic hand controller, but it all proves to be just a gimmick, as this feature is useless at the practical level, and does not work as promised. The Orion Skyquest XT4.5 on the other hand is stripped of all electronic gimmicks but is much easier to operate, and gives fantastic images.
