Assembly of your Red Planet Telescope:

 

Setting Up Your Tripod:

 

The aluminum tripod comes preassembled and ready-to-use. Remove the

 

tripod from the box and pull apart the legs. Gently push down the tripod

 

braces (Fig. 7-35) until they are in the lowest position. Turn the tightening

 

ring (Fig. 7-31) (located at the center of the Tripod Brace) clockwise to lock

 

the tripod in the open position. You can then extend the legs to the desired

 

height by pulling open the tab on each leg lock (Fig. 7-36), sliding the leg

 

down the desired amount and then pushing the leg lock back against the leg

 

into the locked position (Fig. 7-35). Repeat the process with each leg trying

 

to keep the tripod as level as possible with the ground. You will notice there

 

are holes in the tripod leg braces (Fig. 7-33). These are designed to hold eye-

 

pieces when not in use. For added stability you can hang a weight from the

 

tripod hook (Fig. 7-34) located at the bottom middle portion of the tripod.

 

Attaching the Equatorial Mount:

 

Remove the equatorial mount (Fig. 2-10) from the box and twist into the

 

position shown in Fig. 3. Place the bottom of the mount (Fig. 3-20) into the

 

hole in the top of the tripod head and secure with the mount locking screw

 

(Fig. 3-21). Please be careful to make sure that the mount is securely at-

 

tached to the tripod.

 

Attaching the Counterweight:

 

Attach the threaded end of the counterweight bar (Fig. 2-11) into the threaded

 

hole in the equatorial mount (Fig. 2-10). Remove the safety screw from the

 

end of the counterweight bar and set aside for a moment. Slide the counter-

 

weight (Fig. 2-12) onto the bar and tighten down using the screw on the side

 

of the counterweight (Fig. 2-13). Be careful not to drop the counterweight.

 

It is quite heavy and could harm you or damage your floor if dropped. Do

 

not worry about the position of the counterweight just yet. We will position it

 

properly later. Replace the safety screw at the end of the counterweight bar.

 

Attaching the Slow Motion Cables:

 

Locate the two slow motion cables (Fig. 1-7,8). Loosen the screw at the end

 

of each cable so that it does not protrude through the hole. Slide the short

 

cable onto either side of the R.A. shaft (Fig. 1-8) (located at the bottom of

 

the mount) and tighten down with the locking screw. You can place the cable

 

on either side depending on which side is most comfortable for you to use.

 

Slide the longer cable onto the Dec. shaft (Fig. 1-7) (located at the top of the

 

mount) and tighten down with the locking screw. These slow motion cables

 

will allow you to make fine pointing adjustments to the telescope in both

10

R.A. and declination. This will be discussed in more detail later.

Attaching the Telescope Tube to the Mount:

Remove the two cradle rings (Fig. 1-6) from the box. There are two holes in the top of the equatorial mount (called the optical tube saddle plate (Fig.

2-9)). Place the threaded screw at the bottom of each cradle ring (Fig. 6-29) through one of these holes and secure it using the included washer and wing nut (Fig. 6-30). Attach and secure the other cradle ring in the same way.

Make sure that the cradle ring lock knobs (Fig. 6-28) are both on the same side.

Unscrew the locks (Fig. 6-28) on each cradle ring and open them both. Care- fully remove the optical tube assembly (Fig. 1-5) from the box. Gently rest the optical tube into the cradle rings with the focuser (Fig. 1-2) towards the front. The cradle rings should be roughly in the center of the tube. We will balance this later. Close the cradle rings around the telescope and secure by tightening the cradle ring lock knobs (Fig. 6-28).

Attaching the Finder Scope:

There are two finder scope bracket mounting bolts (Fig. 5-27) located at the front end of the optical tube. Remove the nuts and set aside. Place the finder scope bracket (Fig. 5-26) onto the mounting bolts and tighten down securely to the optical tube. Make sure the bracket is facing forward as shown in Fig. 5. Slide the finder scope (Fig. 1-1) into the bracket facing forward. Tighten down the finder scope bracket thumbscrews (Fig. 5-24) to secure the finder scope in place.

Attaching the Eyepieces:

Insert the Kellner 20mm eyepiece (Fig. 1-3) into the focuser (Fig. 1-2) and tighten down using the focuser locking screw (Fig. 4-23).

You have now completed the assembly of your Red PlanetTM telescope. We will now need to make the necessary adjustments in order to use your telescope properly.
