Setting Up Your Tripod:
Thealuminumtripodcomesalmostentirelypreassembledandready-to-use.
Removethetripodfromtheboxandpullapartthelegs.Gentlypushdown
thetripodbraces(Fig.7-36)untiltheyareinthelowestposition.Youcan
thenextendthelegstothedesiredheightbylooseningtheslidinglegexten-
sionlockknob(Fig.7-37),slidingthelegdownthedesiredamountandthen
tighteningtheextensionlockknobuntilsecure.Repeattheprocesswitheach
legtryingtokeepthetripodaslevelaspossiblewiththeground.Youcan
thenattachtheaccessorytray(Fig.7-34)tothetripodbyliningupthethread-
edbottomoftheaccessorytraywiththeholeinthemiddleofthethreetripod
bracesandtwistinguntiltight.Thistrayisdesignedwitheyepieceholder
slots(Fig.7-35)toholdspareeyepieceswhennotinuse.
Attaching the Equatorial Mount:
Removetheequatorialmount(Fig.1-7)fromtheboxandtwistintotheposi-
tionshowninFig.3.Placethebottomofthemount(Fig.1-10)intothehole
inthetopofthetripodheadandsecurewiththemountlockingscrew(Fig.
3-25).Pleasebecarefultomakesurethatthemountissecurelyattachedto
thetripod.
Attaching the Counterweight:
Attachthethreadedendofthecounterweightbar(Fig.1-9)intothethreaded
holeintheequatorialmount(Fig.1-7).Removethesafetyscrewandwasher
fromtheendofthecounterweightbarandsetasideforamoment.Slidethe
counterweight(Fig.1-12)ontothebarandtightendownusingthescrewon
thesideofthecounterweight(Fig.1-13).Becarefulnottodropthecoun-
terweight.Itisquiteheavyandcouldharmyouordamageyouroorif
dropped.Donotworryaboutthepositionofthecounterweightjustyet.We
willpositionitproperlylater.Replacethesafetyscrewandwasherattheend
of the counterweight bar.
Attaching the Slow Motion Cables:
Locatethetwoslowmotioncables(Fig.2-8,17).Loosenthescrewattheend
ofeachcablesothatitdoesnotprotrudethroughthehole.Slideonecable
ontotheleftsideoftheR.A.shaft(Fig.1-8)(locatednearthebottomofthe
mount)andtightendownwiththelockingscrew.Slidetheremainingcable
ontotheDec.shaft(Fig.2-17)(locatednearthetopofthemount)andtighten
downwiththelockingscrew.Theseslowmotioncableswillallowyouto
makenepointingadjustmentstothetelescopeinbothR.A.anddeclination.
Thiswillbediscussedinmoredetaillater.
