Figure 1a: The SkyScanner 100 TableTop Telescope

Congratulations on your purchase of a TableTop telescope. The TableTop will provide years of enjoy- ment of many night-sky treasures including breath- taking views of the Moon, planets, and even some bright deep sky objects. The Maksutov-Cassegrain and refractor models are also suitable for exploring terrestrial vistas.

Your new TableTop is easy to setup and use. It will arrive almost fully assembled out of the box! Only the visual acces- sories need to be installed. These include the EZ Finder II Reflex Sight, the eyepiece, and in the case of the GoScope 80 and StarMax 90, the diagonal.

The following instructions will help you to get the maximum performance from your new telescope, please read them thoroughly.

TableTop Parts (refer to Figure 1a-d):

All TableTop Models:

25mm (20mm for #9541 and #9549) eyepiece: The eyepiece is the part of the telescope that you actually look through to see things. The focal length of the eyepiece and the telescope determines the magnifying power. Magnification is discussed in more detail in the Using Your Telescope section

10mm eyepiece: The higher-power eyepiece that comes with the TableTop. Eyepieces are discussed in the Magnification section.

EZ Finder II reflex sight: This is a special “finder” that helps you aim the telescope and locate objects in the sky for view- ing. The EZ Finder II generates a red LED “dot” that shows where your telescope is aimed. The use of the EZ Finder II is discussed in the Getting Started section.

Optical tube: This is the main component of the telescope.

Altitude tension adjustment knob: By tightening and loos- ening this knob, you can change the amount tension in the altitude (up/down) motion of the telescope.
