Dust Cover: Gently pry 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. Verify that any dew that might have collected during the observing session has evaporated prior to replacing the dust cover.

PBattery Compartments: Insert four (user-supplied) C-cell batteries in each compartment (eight batteries total).

QSmartFinder: Provides an easier way to sight on objects than the main telescope’s eyepiece which has a narrow field of view. To assemble, see the SmartFinder addendum sheet that is included with the manual.

RSmartFinder Alignment Screws: Adjust these screws to align the SmartFinder. See pages 14 and 15 for more information.

SHandbox Holder (refer to Figs. A and B below): Holds the AutoStar handbox in a convenient position on the telescope fork arm handles.

TViewfinder: A low-power, wide-field sighting scope with crosshairs that enable easy cen- tering of objects in the telescope eyepiece.
