For a heavy DSLR, especially with a long lens (more
than 1.5kg or 3.3lbs, including lens), a DEC Mounting
Bracket and a counterweight (CW) and CW shaft are
needed for better balance and performance.
To install the DEC Bracket, remove the Camera
Mounting Block from the mount. Remove the polar
scope cap. Install the DEC Bracket and tighten the
locking screw to secure it. Place the polar scope cap
on DEC bracket.
Install the CW shaft and load the CW.
Loosen two camera mounting block locking screws to
remove the DEC Camera Mounting Block from the
DEC Base on the DEC Mounting Bracket. Attach the
DEC Camera Mounting Block to the bottom of the
DSLR camera and secure it by turning the block.
Reattach the DEC Camera Mounting Block to the DEC
Base and tighten the two locking screws.
Release the RA Clutch Disk while hold the camera.
Slowly move the camera/CW to horizontal position
and balance the load in RA direction by moving the
CW position. More than one CW may be used. Return
the mount to upward position and lock the RA Clutch
Disk again.
4. Set the SkyGuider

Pro
mount to the true north, with the assistance of a
compass. Please note that true north is not
necessarily aligned to the magnetic north from your
compass. Release the Latitude Lock half a turn by
simply rotating the locking lever counterclockwise.
Set the latitude scale at your current latitude by
turning the Latitude Adjustment Knob and retighten
the latitude lock. The latitude lock handle can be
rotated to any suitable position by pulling and
turning. Loosen the two Azimuth Locking Knobs,
adjust the Azimuth Adjusting Knobs to align the polar
axis to the north, and then tighten the Azimuth
Locking Knobs. More details on polar alignment are in
next step.
When power on, the SkyGuider
TM
Pro mount will be
in tracking mode at a rate that shown on the Mount
Status Indicator.
