APPENDIX H:

DE-ROTATER AND

MICROFOCUSER ASSEMBLY

When using a de-rotater, it is important to attach the microfocuser so that it is backed

off slightly from the de-rotater. If the microfocuser is flush against the de-rotater,

the assembly will not work properly. This is true also with other accessories that

may attach up flush against the de-rotater housing. The diagonal mirror (if used with-

out the microfocuser) may be attached tightly as it does not rub up against the

de-rotater housing.

To attach the microfocuser to the de-rotater:

Refer to Fig. 6, page 13, for an exploded view of the microfocuser assembly. Perform

this assembly on a flat surface (such as a desk or a table) before you attach the de-

rotater and microfocuser to the telescope.

1. With the de-rotater on a flat surface, thread on the adapter ring (B, Fig. 6) until it

just touches the housing; then back off the adapter ring (

i.e.

, turn it counter-clock-

wise) one full revolution as shown in Fig. 62.

2. Place the microfocuser over the ring with the "hump" of the microfocuser in the

12:00 position as shown in Fig. 63.

3. Using the provided hex key, tighten to a firm feel one of the three microfocuser hex

screws (K, Fig. 6) up against the adapter ring as shown in Fig. 64. Take care not

to tighten or loosen the adapter ring as you position and tighten the microfocuser

in place.

4. Tighten to a firm feel the other two microfocuser hex screws.

5. Attach the de-rotater to the rear cell of the telescope.

Fig. 62: Back off the adapter ring one

full revolution.

Fig. 63: Place the microfocuser over

the adapter ring. Notice the orienta-

tion of the microfocuser.

cuser hex screws to a firm feel.

12:00 position

Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope

at or near the Sun. Do not look through the telescope as it is moving.
