3.Tighten the acorn nuts with the wrench. Be very careful when doing this so as not to scrape or strip the nuts. Do not overtighten the nuts.

4.Attach the finder scope brackets to the optical tube with the brass thumbscrews (Figure 4).

5.Unthread the six thumbscrews on the finder scope brack- ets until they are flush with the inside of the bracket. Then insert the brass finder scope into the brackets so the large end (objective lens) is facing the front of the telescope, as shown in Figure 1. The grooves on the body of the finder scope should line up with the thumbscrews on the brack- ets. Thread the six finder scope bracket thumbscrews equally until the finder scope is secure in the brackets.

nal into the focuser of the telescope and tighten it with the thumbscrew.

7.Insert the chrome barrel of the 25mm eyepiece into the open end of the correct image diagonal and secure it with the thumbscrew.

Your telescope is now fully assembled and should resemble Figure 1. Leave the dust cover on the front of the telescope when it is not in use.

4. Getting Started

Aiming the Telescope

The Aristocrat 60mm mount permits movement along two axes: altitude (up/down) and azimuth (left/right). See Figure 5. Moving the telescope up/down and left/right is the “natural” way people aim objects and this makes pointing the telescope intuitive and easy.

Aiming in Azimuth (Left/Right)

To move the telescope in azimuth, loosen the azimuth lock knob, take hold of the telescope and gently rotate the tele- scope to the desired position. Then re-tighten the azimuth lock knob.

Aiming in Altitude (Up/Down)

With your hand firmly supporting the focuser end of the tele- scope, loosen the altitude lock lever and lift or lower the tele- scope close to the desired position. As you get close to where you want the telescope to be aimed, tighten the lock lever slightly to increase the tension and make slower, more stable movements. When you are in the desired position, completely tighten the lock lever.

If the altitude movement seems too loose or too tight when the altitude lock lever is completely loosened, you will want to increase the tension on the altitude cradle. Turn the altitude tension discs clockwise or counter clockwise to increase or decrease altitude tension on the mount, using the discs on both sides of the mount. Adjust until the altitude motion feels comfortable for you. Once set, this adjustment will rarely need to be made again.
