Your Explorer Telescope

You have a 'refractor' telescope, which means it has

a long tube with a lens in front and an eyepiece at the

back. The front (objective) lens focuses light to form

an image in the back. The eyepiece is a little

magnifying glass with which you look at

the image.

Since your telescope is lightweight it can

be used as hand-held and is perfect for

carrying in your back-pack and using

on trips, holidays and explorations.

It is especially good for activities

like bird-watching!
