Welcome to a new world of adventure!
Enhanced by the world's most advanced

optical design and cutting-edge optical

processing, iOptron

®

Versa

TM

108 double

air-spaced 108mm Apochromatic doublet

refractor offers a versatile platform that

delivers exceptional performance for both

visual observing and astrophotography. With

outstanding color correction and crisp imaging

you'll be able to view beautiful images through

your eyepiece, CCD camera, or DSLR

camera.

These instructions will help you set up and

properly use and care for your telescope.

Please read them over thoroughly before

getting started.

Getting Started

Your telescope comes fully assembled from

the factory. The optics have been installed

and collimated, so you should not have to

make any adjustments to them. Keep the dust

covers on the telescope when it is not in use.

Mounting the Telescope

The iOptron Versa

TM

108 is a perfect mate for

the iOptron MiniTower™ series goto

altazimuth mount, or the iEQ

®

goto equatorial

mount. You need a dovetail rail (either Vixen

or Losemandy-D type one depends on your

mount’s dovetail saddle) to mount the scope

onto an telescope mount.

Use of Optional Accessories

Your telescope does not come with eyepieces

and diagonal so as to offer the greatest

flexibility in configuring it to your needs.

The 2” compression ring accessory holder

accepts 2” eyepieces, star diagonals, camera

adapters, etc. The 1.25” compression ring

adapter slips into the 2” holder. This lets you

use optional 1.25” accessories (eyepiece, star

diagonal, camera adapter, terrestrial image

erecting diagonal, DSI-type camera, etc.)

Selecting an Eyepiece

Always begin viewing with the lowest power

eyepiece. (Note: a 20 mm focal length

eyepiece has a lower power than a 10 mm

one.) A formula can be used to determine the

power of each eyepiece: Telescope focal

length divided by eyepiece focal length equals

magnification.

Ex. 648mm ÷ 20mm = 32.4X (magnification)

Focusing Telescope

Point the telescope so the front end is aimed

in the general direction of an object you wish

to view. When you first look in the eyepiece,

the image you see may be fuzzy, or out of

focus. If so, gently turn the focus knob with

your fingers until the image becomes sharp.

Go a little bit beyond sharp focus until the

image just starts to blur again. Then reverse

the rotation of the knob just to make sure

you’ve hit the exact focus point. You will have

to readjust the focus when aiming at subjects

of varying distances, or after changing
