4. Attach Accessory Tray
•
Locate the
Accessory Tray (9).
Using the accessory tray bolts, wingnuts and washers (
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
Accessory Tray Braces
are attached as some adjustments may be required.
Your Bushnell Telescope is now ready to be used. To obtain the fullest enjoyment from
your telescope, please refer to the additional information below.
HOW TO USE YOUR NEW TELESCOPE
Astronomical telescopes are designed such that the image you see will appear
UPSIDE DOWN and REVERSED, this is acceptable for viewing celestial bodies.
Selecting an Ocular Lens:
•
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
EYEPIECE focal length =
MAGNIFICATION
(e.g. Using the 20 mm lens, the calculation would look like this: 700 mm
÷
20mm = 35x
or 35 power.)
Focusing Telescope:
•
After selecting the desired
Eyepiece (3)
,
aim
Main Telescope Tube (14)
at a land-based target at least 200
yards away (e.g. A telephone pole or building). Fully extend focusing tube by turning
Rack and Pinion
Focusing Mechanism (2).
•
While looking through selected
Eyepiece (3)
(in this case the 20 mm), slowly retract focusing tube by
turning
Rack and Pinion Focusing Mechanism (2)
until object comes into focus.
Aligning Finderscope:
•
Look through
Main Telescope
Tube (14)
and establish a well-defined target. (see focusing telescope
section) tighten the
Stabilizer Bar Mounting Screw (11)
and
Azimuth Lock Screw (5)
so that telescope’s aim
is not disturbed.
•
Looking through finderscope, alternate tightening each
Finderscope Adjustment Screw
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
Finderscope (1)
will also be centered in the field of view of the
Main
Telescope Tube (14)
.
Never Look Directly At The Sun With Your Telescope
Permanent Damage To Your Eyes May Result.
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
