carefully aligned at the factory to ensure accurate object pointing.
To re-ship the 16” RCX400 commercially, be sure to follow this procedure:
When packaging the 16” RCX400, be sure to release the R.A. lock (13, Fig. 1) and
Dec. lock (17, Fig. 1) to prevent shock to the gears in the motor assemblies should
the package suffer rough handling.

16" TELESCOPE ASSEMBLY
Use the following procedure to assemble your telescope:
To Assemble the 16” Super Field Tripod
The 16” Super Field Tripod (Figs. 58 and 59) for the Meade 16” RCX400 telescope is
supplied as a completely assemb
led unit, e
xcept f
or the spreader bar (
4,
Fig.
58
) and
the six lock-knobs (5, Fig. 58). There are two knobs for each of the three tripod legs.
The
y are used to adjust the le
v
el of the tr
ipod.
These knobs are pac
k
ed separately for
saf
ety in shipment.
F
or most obser
v
ations
, the dr
iv
e base of the telescope’
s fork mount is attached direct-
ly to the super giant field tr
ipod, in the altazim
uth (altitude-azim
uth or v
er
tical-hori-
z
ontal) f
ormat.
The telescope also can be mounted on a per
manent pier in the equator
ial format,
which is set for the latitude of the observing location (see
APPENDIX A, pages 57 through
61, for instructions on using the telescope in equatorial mode). The equatorial mode
per
mits alignment of
the telescope’
s polar axis with the celestial pole
.
After remo
ving the field tr
ipod from its shipping car
ton, stand the tr
ipod vertically, with
the tr
ipod f
eet down and with the tripod still fully collapsed (
Fig.
59
).
Remo
ve the lower
knob (
1, Fig. 58), releasing the tension hub (7, Fig. 58). This knob is used only when
storing the field tripod. Moving one leg at a time, gently pull the legs apart. As the legs
are opened, the tension hub will mo
