Appendix III: The Oponal Equatorial Wedge
If you plan to do a lot of astrophotography with SAM then you should
seriously consider purchasing the Equatorial Wedge (wedge). This
accessory makes the ne poinng control that is necessary for polar
alignment procedures much more easily accomplished than using a
standard lt/pan head or ball mount.
The Equatorial Wedge includes the following key parts:
Mounng Plate: The Mounng Plate includes a 1/4 inch threaded bolt for
aaching a camera or standard camera accessory, such as a ball mount.
Stopper: The Stopper acts as a safeguard against your camera payload
slipping out of the Saddle of the Equatorial Wedge should you let go of it
before ghtening the Mounng Plate Locking Knob.
Azimuth (Horizontal) Adjustment Knob: This knob enables ne poinng
of the wedge in the right and le direcons (azimuth direcons). It is
especially useful when making ne adjustments for the Easy and Advanced
Polar Alignment Procedures.
Altude (Vercal) Adjustment Knob: This knob enables ne poinng of
the wedge in the up and down (altude) direcons. It is especially useful
when making ne adjustments for the Easy and Advanced Polar Alignment
Procedures.
Altude Scale: This scale indicates the altude seng of the wedge. Note
that for polar alignment procedures, the altude of your wedge is equal to
the latude of your observing site if your wedge and tripod are set to level.
Bubble Level: A built-in level to assist you in seng your tripod and
wedge to level. Note that a perfectly level tripod is not a requirement
for using SAM in equatorial mode, but it does make the polar alignment
adjustments a bit easier.
Altude Lock Handle: Loosen this handle slightly before making latude
adjustments, then re-ghten when nished.
