Bushnell 181561 instruction manual Telescope Assembly Instructions, To Use The Finderscope

TELESCOPE ASSEMBLY INSTRUCTIONS

1.Your telescope has adjustable (telescoping) legs (Fig. 1).

2.Stand tripod and expand legs. Loosen the three leg locks. Grab tripod head and lift. Extend the tripod legs to the desired height (at equal lengths) and tighten the knobs on each leg to hold it in position (Fig. 1).

3.Attach the accessory tray (P) to the center leg braces on the tripod legs (Fig 2) and insert accessory tray and bolt through center of tray into braces and tighten bolt.

4.Remove telescope main body from the box. Attach telescope main body (H) by aligning the hole in the telescope saddle with that in the yoke. Screw yoke locking knobs (L) through both holes and tighten the knob.

5.Remove the finderscope (G) with finderscope bracket (F) attached from the box. Remove the two knurled thumbscrews from the telescope main body. Position the finderscope bracket on the telescope main body so that the holes in the base of the bracket line up with the exposed holes in the telescope main body. Replace the two-knurled thumbscrews and tighten securely (Fig. 3).

6.Insert diagonal (D) into the focus tube (C). Secure by tightening small retaining screw on the focus tube (Fig. 4).

7.Insert eyepiece (E) into diagonal (D). Secure by tightening small retaining screw (Fig.5).

Note: In all astronomical telescopes, the image appears upside down. With the use of the diagonal the image appears erect but with a left to right inversion (mirror like). To use the telescope for terrestrial view and to correct the mirrored image, insert the erecting eyepiece in between the diagonal and the eyepiece. We recommend the use of the low magnification eyepiece when the telescope is used for terrestrial viewing. Only refractor telescopes come with erector eyepieces. Reflectors (mirrors) are used mainly for astronomical purposes.

The telescope is now fully assembled and ready for use.

8. To use the Barlow, insert Barlow between the diagonal and the eyepiece. Secure by tightening small retaining screw. Insert eyepiece into open end of Barlow and secure.

CAUTION! Viewing the sun can cause permanent eye damage.

Do not view the sun with this telescope or even with the naked eye.

TO USE THE FINDERSCOPE

The finderscope is a small low-powered and wide field of view telescope mounted alongside the main telescope and is used to search for the target and aim the main telescope at it. But before you can use the finderscope, you will need to line it up with the telescope. This procedure will become easier with practice.

1.Install the lowest power eyepiece (25mm) into the eyepiece tube. Pick out an easily recognized, unmoving object no closer than a thousand yards away. Aim your telescope toward your object until its image is centered in the eyepiece. Lock all the knobs on the mount so the telescope will not move.

2.Look through the finderscope. If the object you lined up in the telescope is not visible, loosen the adjustment screws and move the finderscope around until you see it. Once it gets within range, tighten the adjustment screws while centering the object in the scope. You will note that the image will shift toward the screw you are tightening (Fig. 6).

3.Adjust screws to center object on the finderscope cross hairs. Recheck your telescope to make certain it is still on target. If it moved, realign it and adjust your finderscope. If it hasn’t, you’re all set. Your finderscope is now operational.
