Never Look Directly At The Sun With Your Telescope

The equatorial mount is designed to move in any direction. It can be set to allow manual controls to track the movements of celestial bodies across the sky. This is referred to as diurnal movement; movement of celestial bodies in the direction opposite to that of the earth’s rotation and is around the earth’s axis.

By aligning the telescope’s polar axis at celestial North, you will place the telescope in parallel with the earth’s axis and thus be able to locate stars in the sky based on star atlas information. To compensate for your position on earth, the polar axis is set in one of three ways:

∙Set up the telescope at night. Loosen the declination axis lock screw (use adjustment tool provided) and rotate the telescope around the declination axis until the arrow on the declination scale points to 90 degrees. Tighten the declination axis lock screw. The telescope is now roughly in parallel with the polar axis.

∙ Loosen the horizontal axis lock screw and turn the telescope until the objective end faces due north. This can be done by approximating the location of the pole star (Polaris or North Star)

or by the use of a compass. True North is then found by directing

the telescope at Polaris, as magnetic North is slightly away from true North.

∙ Look up the latitude of your area in any geographical atlas. Loosen the latitude lock screw and set the latitude scale to the correct latitude for your area. Aim the Finderscope at Polaris. You will probably notice that Polaris is not dead center in the finderscope’s field of view. This is probably because your telescope is not absolutely level with the ground. Loosen the

horizontal axis lock screw again and turn the telescope so that it is directly aimed at Polaris. Tighten both the horizontal axis lock screw and the Latitude Lock Screw. Polaris is 1 degree of the North celestial pole. Therefore, the sighting of stars will have to be slightly adjusted as you locate them in the heavens.

IV. TIPS FOR USING YOUR TELESCOPE

Focusing the Telescope

∙Aim the main telescope tube at a well-defined target, at least 200 yards away (e.g. a telephone pole or building). Fully extend the focusing tube by turning the rack and pinion focusing mechanism (16).

∙While looking through the Eyepiece Lens (19), slowly retract focusing tube by turning the rack and pinion focusing mechanism until object comes into focus. (Note: The image will be upside down and reversed.

This is a normal occurrence in astronomical telescopes. )

Aligning the Finderscope

∙Locate an object at least 200 yards away. Tighten the Latitude Lock Screw (fig 5.) so that telescope’s aim is not disturbed.

∙Looking through the Finderscope (21), adjust the Finderscope Adjustment Screws (22) until the crosshairs of the Finderscope are precisely centered on the same object already centered in the field of view of the Main Telescope Tube. (Note: image in finderscope will be upside down and reversed.)

∙Objects located using the finderscope will also be centered in the main telescope’s view.
