LT QUICKSTART GUIDE Place the eyepiece into diagonal prism.
It is best to set up the telescope in twilight or before sunset the first time you use the LT. Take the telescope and tripod outside. Set the telescope in a large open area where you can see lots of sky. Make sure the ground is stable and is approximately level. It is best to set up the scope away from bright nighttime lighting. Bright lights will spoil your night vision and impede your ability to see the sky.

Look though the red dot finder, a bright star will be in the field of view. Use the arrow keys to put the red dot on the star. Looking through the eyepiece, center that star, using the arrow keys. Press “ENTER” when completed. If an object obstructs the view of the sky, press the up or down scroll keys (Ref. 14) and AutoStar will slew to another alignment star.

Repeat for the second alignment star. AutoStar will display “Alignment Successful” when you have successfully centered two alignment stars. The display then reads “Press 0 for tour or mode for menu”. Press “0” and AutoStar will take you on a guided tour of the night sky. Important Note: If you have updated or replaced your Autostar #497 hand box, please make sure the telescope type “LX90-8” has been selected and the setting of Az/RA Ratio is +02.75075 and Alt/DEC Ratio is -02.75075. These are essential setup settings to get your LT-6/ LT-8 telescope right working.
