Shop for Telescopes from Telescopes.com! When I first started in amateur astronomy I did as most beginners and purchased a department store telescope that advertised the most power. (700x I believe) Unfortunately again like most beginners I found that the advertised power was impossible due to the size of the telescope and more importantly the lack of stability of the mount. Time and again I speak to parents and children who tell me how frustrated they are that after finding Saturn in a beginner telescope they can t get a good view of the rings because the mount is too shaky or the telescope controls too difficult to adjust. I hear many tell me that they tried once many years ago and now the scope is sitting in a closet collecting dust! The NEW Porta Mount II is an easy to use light... Less

Here is an engaging way to help your students explore how concave and convex lenses refract light to produce real and virtual images. Students measure the lenses' focal lengths and discover how lens pairs can be used to make 2 different types of refracting telescopes. From the determined focal lengths, students calculate their telescopes' magnification powers.Kit includes instructions, activities, and materials to build 8 hand-held refracting telescopes (4 Galilean and 4 Keplerian), each with a 444-mm-focal-lengt h objective lens and a 50- or 150-mm-focal-lengt h eyepiece lens.
