How to Autoalign the Meade LX90 GPS Schmidt-Cassegrain Telescope

You don't have to be a professional astronomer to align your Meade telescope. Any amateur star-gazer who can press a button can accomplish the task. Here's how to do it.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:

• Meade LX90 GPS Schmidt-Cassegrain telescope

1. Check that the telescope's locks are tight and that you have correctly attached AutoStar is to the telescope.
   
2. Turn on the telescope.
   
3. When "Press 0 to Align or Mode for Menu" appears on the display, press "0" to start automatic alignment.
   
4. "Automatic Alignment" will appear on the display. The telescope will automatically perform several procedures such as detecting the level of the base of the telescope, finding north and attempting a GPS fix.
   
5. Next, the telescope will orient itself. You will first see "Automatic Alignment: Selecting Star and Slewing" on the display. "Center Brightest Star: Press Enter" will eventually appear on the display. Use the "Arrow" keys to center on the brightest star in the area and press "Enter."
   
6. The telescope will move to the second alignment star. "Center Brightest Star: Press Enter" will appear on the display. Use the "Arrow" keys to center the alignment star in the eyepiece and press "Enter."
7. You should see "Alignment Successful" on the display.
   

Tips & Warnings

• If you see "Alignment Unsuccessful" in the display in Step 7, repeat Step 6.
• If a building or other object is in the way of your view in Step 5, press the "Scroll Down" key to align on another star.
