HowtoalignpolarscopeopticalaxistomountRAaxis:
Ifyouaresuspectingthatthepolarscopemay
bemisaligned,youmaycheckitbyputtingastarinthe
centerofthepolarscopereticlecrosshairsandrotating
mount’sRAaxis.Ifthestarstaysinthecenterofcross
hairs,thepolarscopeisalignedtothemount’sRAaxis.
Intheeventthepolarscopeopticalaxisneeds
tobeadjusted,youcandothisprocedureatnightwhile
pointingatPolaris,oranybrightstar.However,itis
probably easier to do it during the daytime using a
distantpoint,suchasa flagpoleortop of a buildinga
coupleofhundredyardsaway,asyourtarget.
1. MounttheSkyGuiderProontoatripod.
2. Release RA Clutch Disk slightly so the polar scope
canberotated.

3. Removepolarscopecoverandbase.

4. Rotatethepolarscopesothatthe12o’clockmark
is leveled on the right side. Adjust the AZ base in
altitudeandazimuthtocentertheobjectontothe
crosshairs.
5. Rotate the mount 180 degree to bring the 12
o’clockmarktotheleftside.
6. Bring the object half the distance to the center by
adjusting the reticle adjustment set screws using a
1.5mmhexkey.Keepinmindthattheimageinthe
finder is inverted. Loose one screw first, then
tighten the other screw(s). Only loose/tighten one
screwandsmallturnsatatimetoavoidthereticle
lostitsposition.Itmaytakeafewminutestoget
familiarwiththescrewsthatmovethepolarscope
in the appropriate direction. PLEASE do not over
tightenthesetting screws (you’llbreakthereticle
holderorreticle).

7. AdjusttheAZbaseinaltitudeandazimuthtocenter
theobject.
8. Rotatethemount180°tobringthe12o’clockmark
backtotherightside.Ifyouare luckyenough,the
object will stay at the center of the polar scope.
Otherwise, repeat Steps 4 ‐ 6 to further move the
objecttothecenter.
