vents the telescope from being moved manually, but engages the verti-

cal motor drive for AutoStar II operation.

1* Dust Co

ver:

Gently pr

y the dust cover from the front lens of the telescope.

Note: The dust cover should be replaced after each observing session and the

power turned off to the telescope.

1( Optical Tube: The main optical component that gathers the light from distant

objects and brings this light to a focus for examination through the eyepiece. The

tube contains the primary mirror which floats on a layer of adhesive that results

in zero-stress to the glass and no distortion to the optics.

2) Fan: AutoStar controls the fan operation. The amount of time required to stabi-

liz

e the temperature will be dependent upon ambient conditions including the

observation site and preexisting condition of the telescope. The fan should be

activated at the beginning of the observation session to accelerate the tempera-

ture stabilization. As soon as the optics have reached an equilibrium with the

environment the fan should be turned off. Fan operation time should range

between 5 and 25 minutes. While it is permissible to run the fan continuously it is

not recommended because the very slight vibration of the fan may cause notice-

able movement of the objects observed in the sensitive optics.

The Viewfinder

2! 8 x 50mm Viewfinder: A low-power, wide-field sighting scope with crosshairs

that enables easy centering of objects in the telescope eyepiece.

2@ Viewfinder Objective Lens: Gathers the light for the viewfinder.

2# Viewfinder Locking Ring: Locks the objective lens into place. Unlock to adjust

the focus of the objective lens. See page 18 for details.

2$ Viewfinder Adjustment Screws: Use these six screws to adjust the alignment

of the viewfinder.

2% Viewfinder Eyepiece/Focuser: The eyepiece magnifies the image collected by

the viewfinder’s objective lens. Rotate the eyepiece to focus.

2^ Viewfinder Bracket and Mounting: Holds the viewfinder in place.

The Tripod

2& Tripod Base with Leg Receptacles: Attach the mounting base (see 1@) to the

tripod base. See page 16 for mounting instructions. Slide the tripod legs into the

leg receptacles.

2* Leg Attac

hment Lock:

Secures the tr

ipod legs into the leg receptacles.

2( Sliding Inner Leg Extension: Inner leg extension slides in or out to adjust the

tripod height.

3) Variable Height Tripod Legs: Supports the optical tube assembly.

3! Locking Latch and Thruster Bar: Lift latch to release inner leg extensions. Let

go of latch to loc

k inner extension in place. See page 16 for mounting
