3. Make sure that the microfocuser is plugged into the computer
control panel focus port.
4. Point the telescope at a bright star.
5. Rotate the mirror lock knob towards the "unlock" posi�on, un�l it
feels loose. Use the coarse focus control to achieve a rough focus of the
star (see Fig. 4.)
6. Rotate the mirror lock knob towards the "lock" posi�on and adjust
the tension to a firm feel; this ac�on serves to lock in the coarse focus.
Important Note: Do not use or bump the coarse focus knob once you
have set the coarse focus. If you do so, repeat steps 5 and 6 above to
reset the coarse focus.
7. Press the Focus key (Number key "4"). "Focus Control: Speed: Fast"
displays. Press the Up or Down Scroll keys to cycle through the four
speed op�ons. Press ENTER to select the desired speed. Or press one of
the following Number keys a�er pressing the Focus key to change the
speed:
Key # Speed Key #

9. You may need to repeat this procedure when you change
eyepieces.
Use with Meade De-Rotater
When using a Meade de-rotater, it is important to a�ach the microfo-
cuser so that it is backed off slightly from the derotater. If the microfo-
cuser is flush against the de-rotater, the assembly will not work proper-
ly. This is true also with other accessories that may a�ach flush against
the de-rotater housing.
To A�ach the Microfocuser to the De-rotater:
Refer to Fig. 1. Perform this assembly on a flat surface (such as a desk or
a table) before you a�ach the de-rotater and microfocuser to the
telescope.
1. With the de-rotater on a flat surface, thread on the adapter ring un�l
it just touches the housing; then back off the adapter ring (i.e., turn it
counter-clockwise) one full revolu�on as shown in Fig. 6.
2. Place the microfocuser over the ring with the "hump" of the microfo-
cuser in the 12:00 posi�on as shown in Fig. 7.
3. Using the provided hex key, �ghten to a firm feel one of the three
microfocuser set screws against the adapter ring as shown in Fig. 8.
Take care not to �ghten or loosen the adapter ring as you posi�on and
�ghten the microfocuser inplace.
4. Tighten to a firm feel the other two microfocuser set screws.
5. A�ach the de-rotater to the rear cell of the telescope.
