lock counterclockwise unlocks the telescope enabling it to be freely rotated by
hand about the R.A. axis. Turning the R.A. lock clockwise (to a firm feel only)
tightens the lock and prevents the telescope from being moved manually, but
engages the R.A. motor drive (see
2%
) for Autostar or EC handbox operation.

Dec. Motor Drive Assembly: Controlled by Autostar or the EC handbox. Moves
the optical tube along the Dec. axis. The Dec. Lock (see

thread the shaft into the tripod mounting base/mounting base (see 3& ) and
tighten to a firm feel to secure the tray to the tripod and keep the tripod stable.

Spreader Bar: Holds the tripod legs securely in place and also acts as a holder
for extra eyepieces.

Tripod Mounting Base: Set the telescope mount into the tripod mounting base
and secure into place using the T-handle lock and shaft. See

Join an Astronomy Club, Attend a Star Party
One of the best ways to increase your knowledge of astronomy is to join an astronomy
club. Check your local newspaper, school, library, or telescope dealer/store to find out if
there’s a club in your area.
At club meetings, you will meet other astronomy and Meade enthusiasts with whom you
will be able to share your discoveries. Clubs are an excellent way to learn more about
observing the sky, to find out where the best observing sites are, and to compare notes
about telescopes, eyepieces, filters, tripods, and so forth.
Often, club members are excellent astrophotographers. Not only will you be able to see
examples of their art, but you may even be able to pick up some “tricks of the trade” to
try out on your
LXD75-Series telescope. See page 36 for more information about pho-
tography with the LXD75-Series .
Many groups also hold regularly scheduled Star Parties at which you can check out and
observe with many different telescopes and other pieces of astronomical equipment.
Magazines such as Sky & Telescope and Astronomy print schedules for many popular
Star Parties around the United States and Canada.
