Discovery Sky Trip ST50 Telescope with book

Discovery Sky Trip ST50 is a compact entry-level refractor telescope that is perfect for your first introduction to outer space. You can use it to view the Moon and planets as well as to zoom in on terrestrial objects when using the instrument as a powerful spotting scope. When it comes to observing deep space objects, the telescope allows you to see the brightest celestial objects. The telescope is easy to operate: an alt-azimuth mount allows the tube to be moved up and down and from left to right.

The Discovery Sky Trip ST50 telescope comes with many accessories and the "Space. Non-Empty Emptiness" knowledge book. Beginners will be able to learn fascinating information about stargazing and put that knowledge into practice. The eyepieces with different focal lengths and a Barlow lens allow you to experiment with a magnification rate; and an optical finderscope helps you successfully find specific objects in the sky. Adjustable height tripod adjusts for the height of an observer.

One of the main advantages of this model is an ultra-compact optical tube: almost half as long as many other refractors. Therefore, the telescope is easy to take with you on trips or to the countryside. In addition, the kit includes a special-purpose backpack for the comfortable transportation of the device and its accessories. A smartphone adapter enables you to try your hand at astrophotography and capture the moments of exploring outer space.
