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.
