Scopeandpolaraxiscovers.Lookthroughthepolar
scopetolocatePolaris(orSigmaOctantisatsouthern
hemisphere). Slightly loosen the Azimuth Locking
Nuts and Latitude Locking Clamps. Use the two
AzimuthAdjustmentKnobsonthesidetocenterthe

PolarScope.
(1) Connect the Polar Scope illumination LED to the
ReticlesocketlocatednexttoDECdriveunit(see
insert above). Turn the mount power on. Use
Hand Controller (“Settings” => “Polar Scope
Brightness”)tosettheilluminationintensity.
(2) Use Hand Controller (MENU=>“Alignment” =>
“Position of Polaris/SigmaOct”)todisplaythePolaris
PositionontheLCDscreen,asindicatedbelow.For
example,June22,2014,20:19:42inBoston,US(long.
W71°08’50” and lat. N42°30’32”, UTC ‐300 min,) the
