scope), you can use Autostar to control both the RCX and the microfocuser. Make sure you have connected the saddle plate to the RCX and the microfocuser to your tele- scope and also the saddle plate's Focuser port. Follow this procedure:

•Press the Number Key 4 and Autostar displays "OTA: Fast" displays. You are now in control of the RCX focuser.

•Use the Up/Down keys to scroll through the RCX focuser speeds.

•Press the Number Key 4 again and "Define Presets" displays. Define the RCX presets as described earlier.

•Press the Number Key 4 and Autostar displays "Saddle Focus: Speed Fast." You are now in control of the microfocuser focuser.

•Use the Up/Down keys to scroll through the four microfocuser speeds.

•Use the Up and Down arrow keys to move the focus in or out.

Press MODE to exit the Focus menu at any time.

To select a previously defined focus preset

1.Press the Focus key twice. “Focuser Preset: Go To Preset” displays. Press ENTER to select this menu.

2.Use a Scroll key and scroll down the list of previously defined presets. When the desired preset displays (for example, “Deep Sky Imager”), press ENTER.

Important Note: If you do not park your telescope, you will need to select one of the presets and refocus your telescope using the Sync On menu. See TO SYNC ON A FOCUS PRESET below.

To sync on a focus preset

If you park your telescope, AutoStar II remembers all the focus positions you defined as presets and you will not need this menu.

If you do not park your telescope, you will need to select just one of the presets and refocus your telescope using the Sync On menu. Then AutoStar II will reset all the other presets back to the focus preset positions you previously defined.

1.Press the Focus key twice. “Focuser Preset: Go To Preset” displays. Use a Scroll

key and scroll until “Focuser Preset: Sync On Preset” displays and press ENTER to select this menu.

2.Use a scroll key to choose one of the previously entered presets from this list (the most likely preset you will choose will be one that accounts for your own eyesight).

3.Use the Up or Down Arrow keys to focus the eyepiece.

4.Press ENTER. AutoStar II now “remembers” the relative focus positions of the eyepiece.You can now choose any preset and it will be correctly focused.

To exit the focus operation at any time:

1.Press MODE.

Slew Speeds

Autostar II has several slew speeds that move the optical tube at rates that are directly proportional to the sidereal rate and have been calculated to accomplish specific func- tions. Press the Speed key (Number key "1") and then press a Number key to change the slew speed, which is shown for about two seconds on Autostar II’s display.

The available speeds are:
