#4 A Terrestrial 10X Hand Telescope

Kepler’s telescope greatly improved on Galileo’s in terms of its magnification

and field of view. However, Kepler’s telescope, like Galileo’s produced an
inverted (upside down) image.

The inversion is caused by the convex sides of the magnifying lens directing

the light waves past each other, top to bottom and side to side.

Inversion Lenses (05) used in pairs can be used to make the image appear

through the telescope as it does in nature.

The Terrestrial 10X Hand Telescope is useful for seeing things on earth, at a

distance greater than 10 meters (32-1/2 feet).

To assemble the Terrestrial 10X Telescope

Fit the Objective Lens (08) into the Body (01) at the end with the decorative

covering.

Fit the short end of Collecting Lens (04) into the end of the Drawtube (02).

From the other end of the Drawtube, insert 13mm Spacer (12) until it touches

the end of the Collecting Lens.

Next insert Inversion Lens (05) with the marking toward Spacer (12).

Next insert 16.2mm Spacer (13)

Now insert the other Inversion Lens (05) with the marking “5” to the outside

facing away from 13mm Spacer (12).

Insert the Symmetric Eyepiece (07).

Insert the Collecting Lens (04) into the Body (01) to join the two parts of the

telescope together.

You can now focus the telescope on objects more than 10 meters away by

adjusting the Eyepiece.
