3-_” bolts, 6-_”

washers and 3-wingnuts)

 connect the 

Accessory Tray  

to the

 Accessory Tray Braces (8)

. Start with one tripod

leg and attach wingnuts. Wingnuts should be positioned beneath the accessory tray. Do not tighten
wingnuts until all 

 are attached as some adjustments may be required.

  You should always start viewing with the lowest power eyepiece, which in this case is the 20 mm lens.

Note: the base power of each ocular lens is determined by the focal length of the telescope objective
lens, which for this model is 700 mm. A formula can be used to determine the power of each eyepiece:
Telescope  OBJECTIVE  lens  (Primary  Mirror)  focal  length 

MAGNIFICATION (e.g. Using the 20 mm lens, the calculation would look like this: 700 mm 

÷

 20mm = 35x

or 35 power.)

After selecting the desired 

Eyepiece (3),

 aim 

 at a land-based target at least 200

yards away (e.g. A telephone pole or building). Fully extend focusing tube by turning

  While looking through selected 

 (in this case the 20 mm), slowly retract focusing tube by

turning 

 until object comes into focus.

  Look through

section)   tighten the

is not disturbed.

  Looking through finderscope, alternate tightening each 

 until crosshairs of

finderscope are precisely centered on the same object already centered in main telescope tube's field of
view.

  Now, objects located first with the

Enjoying Your New Telescope
1.  First determine your targeted object.  Any bright object in the night sky is a good starting point.

One of the favorite starting points in astronomy is the moon.  This is an object sure to please any
budding astronomer or experienced veteran.  When you have developed proficiency at this level,
other objects become good targets.  Saturn, Mars, Jupiter, and Venus are good second steps to take.  

2.  The first thing you need to do after assembling the telescope as planned is center the desired object

in the finderscope's cross hairs.  Provided you did a reasonable job aligning the finderscope, a quick
