(See Fig 31). Manually rotate the counterweight shaft

so it is parallel to the ground. Continue to keep your

hand on the counterweight shaft to control rotation.

Loosen Counterweight: Loosen the lock knob

on the counterweight so it is free to move. Slide the

counterweight along the counterweight shaft so that

the mount head does not rotate in either direction and

is properly balanced. Lock the RA axis when balance

is achieved.

Note: If your telescope came with additional

weights you may need to attach counterweight shaft

extension pieces to achieve balance. Your telescope

is now balanced in both DEC and RA axes and will

perform optimally.

Return to Alt-Az Mode: Insert the LX80 tool into the

hex headed latitude adjustment, twisting the tool in a

counter clockwise direction to bring the mount head

back up to a vertical (alt-az) confi guration. This can

be checked by lining the latitude indicator back at 90°

degree mark.

Aligning the Viewfi nder

The wide fi eld of view of the telescope’s viewfi nder

(Page 8, Fig 1, 1) provides an easier way to initially

sight objects than the main telescope’s eyepiece

(Page 8, Fig 1, 6), which has a much narrower fi eld of

view. If you have not already attached the viewfi nder

to the telescope tube assembly, follow the procedure

described in Step 7, Page 17.

In order for the viewfi nder to be useful, it must be aligned

to the main telescope, so that both the viewfi nder and

telescope’s optical tube (Page 8, Fig 1, 17) point at

the same position in the sky. This alignment makes it

easier to fi nd objects by fi rst locating an object in the

wide-fi eld viewfi nder, then looking into the eyepiece of

the main telescope for a detailed view.

To align the viewfi nder, perform steps 1 through 4

during the daytime; perform step 5 at night. Refer to

Figs 1 and 2.

1. Remove the dust covers from the optical tube

(Page 8, Fig 1, 18) and the viewfi nder.

2. If you have not already done so, insert the low-

power SP 26mm eyepiece (Page 8, Fig 1, 6) into

the accessory adapter of the main telescope. See

step 8, Page 17.

3. Look through the viewfi nder eyepiece at an object
