11)Locate the finderscope. Remove the knurled nuts on the threaded posts at the focuser end of the telescope tube. Mount the finderscope bracket by placing the bracket over the posts protruding from the tube and tightening it down with the knurled nuts. Orient the finderscope so that the large lens is facing towards the front of the tube. See figure 3

12)Remove the lens cap from the front of the telescope.

Aligning the Finderscope

Figure 2

1)Locate a distant daytime object and center it in a low power eyepiece in the main telescope.

2)Look through the finderscope and take notice of the position of the same object.

3)Without moving the main telescope, turn the adjustment thumb screws located around the finderscope bracket until the crosshairs of the finder are centered on the alignment object.

Using the Barlow Lens

1)Your telescope also comes with a 3x Barlow lens which triples the magnifying power of each eyepiece (see Magnification section of the manual). To use the barlow lens, remove the diagonal and insert the barlow lens directly into the focuser. Then start by using the low power eyepiece such as the 20mm, and insert it either directly into the barlow lens or into the diagonal. See Figure 4.

TELESCOPE OPERATION  USING YOUR TELESCOPE

Moving Your Telescope:

To change the direction your telescope is pointing:

1.To move the telescope in declination (north/south) there are two options. For large and quick movements, loosen the declination knob (see figure 9) when moving the telescope and then tighten the knob when you are near the position you want. For very small movements and fine adjustments, use the declination cable. The declination cable has a range of about 30° and if you come to the stop at the end of its travel, do not try to force movement when the declination cable has reached the stop. Instead loosen the declination knob and manually move the telescope in declination until you pass the object in the opposite direction. Then tighten the knob and reverse the direction of the declination cable.

2.To move the telescope in right ascension (east/west) there are two options. For large and quick movements, loosen the right ascension knob (#11) when moving the telescope and then tighten the knob when you are near the position
