Main technical features


This telescope ensures that you will not notice any spherical aberration when you examine the planets through its lens. You will be able to observe moving targets, as well, such as comets, due to the fast focal ratio available on this particular model.

Another thing that makes many people adore this model is the fact that no setup is required; you take the telescope out of the box, and you start examining the night sky with its help.

Many users appreciate this telescope because of how portable it is; its total weight allows you to grab it and carry it around with you without a problem; that makes it ideal for trips away from home.

The telescope has a large aperture, which grants it fantastic light gathering abilities, which, in turn, provide the user with sharp, bright images of the celestial objects in the sky.

In-depth information


The image quality available for a telescope is paramount, and it allows you to explore the night sky as you see fit. This particular model comes equipped with a parabolic mirror whose primary purpose is to reduce the spherical aberration that is usually associated with this type of optical tool. You also get a sharp image of the celestial objects you examine.

The fast focal ratio is one of the most important traits of this telescope, and it provides the user with a wide field of view, which, in turn, allows him or her to observe moving targets such as comets with maximum accuracy. You will appreciate how in-depth you can explore space objects and even clusters of stars and galaxies.

One thing that many people appreciate about this model is the fact that there is no setup to worry about. Using the steel tripod supplied with the purchase, you will be able to manipulate the telescope, as you take in the night sky and you follow your preferred celestial bodies with your eyes.

Are you planning an astronomy trip? Instead of just relying on equipment that may be provided at observatories across the world, decide in favor of this model. It is lightweight, and easy to carry around, so you won’t have to go anywhere without it.

The image quality provided by this model is excellent, and, for the most part, that happens due to the large aperture. The optics mechanism is capable of gathering enough light to render a crisp, bright image for the user, and that helps when you want to observe, for instance, the rings of Saturn, in the highest detail possible.

Known issues


The manufacturer only offers two eyepieces – 10mm and 20mm – which means that, if you want to increase magnification, be prepared to invest a bit in some extra accessories. This is the most common complaint of those who have bought and tried this model, and, otherwise, they say they are satisfied with it.
