W ARNING! Never use a Meade ® LX80 T elescope to look at the Sun! Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope at or near the Sun. Do not look through the telescope or [...]

Balancing the T elescope In order for the telescope to be stable on the tripod and also for it to move smoothly , it must be properly balanced in both vertical and horizontal axes. The horizontal axis is commonly referred to as the DEC (Declination) axis and vertical axis the RA (Right Ascension) axis. Most of the motion of the telescope takes plac[...]

( See Fig 31 ). Manually rotate the counterweight shaft so it is parallel to the ground. Continue to keep your hand on the counterweight shaft to control rotation. Loosen Counterweight: Loosen the lock knob on the counterweight so it is free to move. Slide the counterweight along the counterweight shaft so that the mount head does not rotate in eit[...]

satellites are in low orbit, travelling at approximately 17,500 mph. When visible, they move quickly across the sky and are only in the fi eld of view for a few minutes, requiring AudioStar to slew the telescope rapidly . Best viewing is near Sunrise or Sunset when the sky is still dark. Viewing in the middle of the night can be problematic becaus[...]
