ATTACHING THE FINDER SCOPE
(1)Backouttheadjustmentscrewon
thefinderbrackettoallowpassageof
thefinderscope.(Makesurethe
adjustmentscrewsdonotfalloffthe
bracket.)
(2)SidetherubberO‐ringontotheeyepieceend
ofthefinder.Therearetwogroovesonthefinder
tube.PositiontheO‐ringonthenarrowgrooveat
themiddleofthefindertube.
(3)Pullupthefixedstudon
thebracketringandpullit
sothatthefindertube
slidesintothebracketring
fromitseyepieceend.
Releasethefixedstudso
thewidegrooveonthe
findertubeisunderneath
thestud.
(4)Tightenthetwoadjustmentscrewssothatthe
finderscopeis
alignedasshown
inthefigure.

Loosenthefinderbracketlockthumbscrewonthe
telescope.
Attachthefinderbracketasshowninthe
figure,tightenthefinderbracketlock
thumbscrewsecurely.
ALIGNING THE FINDER SCOPE – Besuretoalignthefinderscopebeforeyoubegin
observing.
(1) Chooseaconspicuoustargetinthedistanceandplacethetargetin
thecenterofthefieldofviewofthetelescope.(Intheillustration,a
distanttowerisbroughtintothecenterofthefieldofviewofthe

(2) Next,lookthroughthefinderscope.Youshouldprobablyfindthe
sametargetsomewherewithinthefinder’sfieldofview.(The
finderscopehascrosshairs.)
(3) Aligntheopticalaxis(fieldofview)ofthefinderscopewiththe
opticalaxis(fieldofview)ofthetelescope.Adjustthefinderscope
bylooseningortighteningtheadjustmentscrewsAandB(InFigure
