What can this telescope do?
An ideal first telescope for all ages. With the 76mm appature you can see up to the moon and further to comets and more. The telescope comes with two different lenses, one with 15 times magnification and one with 30 times magnification.

Why choose a reflector telescope?
Reflector telescopes are open at one end and uses mirrors to collect and focus the light for the image. Typically reflector telescopes have larger apertures than refractors and can see further and fainter objects with a wider apparent field of view. Reflector telescope can be made smaller for the same magnification and don’t suffer from chromatic aberration (colours appearing around an image) as some refractors can. The image in the telescope eyepiece will appear upside-down this is normal for a telescope set up for astronomical viewing.

This Celestron firstscope is simple and easy to assemble. Just attach the finderscope, insert the eyepiece and you’re ready to stargaze. The telescope can be placed on a desktop or any flat surface and with its Dobsonian style mount it can rotate on its base as well as up and down to easily point your telescope at anything you find.

Why is this telescope special?

This stylish and useful telescope is a brilliant edition to anyone’s hobby. It is lightweight and portable and can easily be moved about for the best view.
