Collimation of the Optics:
Theinternalopticsofthetelescopehavealreadybeen“collimated”or
“aligned”atthefactory.However,roughhandlingofthetelescopemay
knock the optics out of collimation, resulting in poor optical performance.
Please refer to Fig. 9 to better understand the internal layout of your
telescope. To determine if your telescope needs collimation perform
the following steps:
•Removetheeyepiece(Fig.1-3)fromthefocuser(Fig.1-2)andturn
thefocusingknob(Fig.1-4)untilthetubeisatitsinnermostposition.
•Pointthetelescopeataplainbackgroundandthenpeerthroughthe
empty focuser. You should see a series of concentric circles
(SeeFig.10).Theoutermostcirclebeingareectionoftheprimary
mirror(withthreemirrorclips).Theinnercircleisthediagonal
mirror, which should be precisely centered inside the primary mirror.
Youshouldseethereectionofyoureyeinthediagonalmirror.
Adjusting the Diagonal Holder:
Ifthetelescopeisproperlycollimatedyoushouldseetheprimarymirror(See
Fig.10)andthreeclipsintheirentirety.Iftheprimarymirrorisnotcentered
properly(SeeFig.11)youwillneedtoadjustthediagonalmirror(SeeFig.9)
tocorrectthis.Loosenthediagonalmirrortiltscrews(Fig.7-26)sothatyou
canmovethediagonalholder(Fig.7-27)withyourhand.
Tilt the diagonal holder until the entire primary mirror is visible and carefully
retighten the screws to lock it into place. If necessary, turn the three screws
slightlytomakeneadjustments.
