Attaching the Telescope Tube to the Mount:
Removethecradlering(Fig.1-4)fromthebox.Thetopoftheequatorial
mountiscalledtheopticaltubesaddleplate(Fig.2-16).Loosenthesaddle
platelock(Fig.3-19)andslidethecradleringintothesaddleplateuntilthe
stopperonthebottomofthecradleringassemblyrestsagainstthefrontof
thesaddleplate.Makesurethatthecradleringlockknob(Fig.6-33)ison
therightsideofthemount.Tightenthesaddleplatelocktosecurethecradle
ring in place.
Unscrewthecradleringlockknob(Fig.6-33)andopenthecradlering.
Carefullyremovetheopticaltubeassembly(Fig.1-3)fromthebox.Gently
resttheopticaltubeintothecradleringwiththeeyepiece(Fig.2-14)towards
theback.Thecradleringshouldberoughlyinthecenterofthetube.We
willbalancethislater.Closethecradleringaroundthetelescopeandsecure
bytighteningthecradleringlockknob(Fig.6-33).
Attaching the Finder Scope:
Therearetwonderscopebracketmountingbolts(Fig.4-29)locatedatthe
endoftheopticaltubeneartheeyepieceassembly.Removethenutsandset
aside.Placethenderscopebracket(Fig.4-28)ontothemountingboltsand
replacethenuts,tighteningdownthebracketsecurelytotheopticaltube.
MakesurethebracketisfacingforwardasshowninFig.4.Slidethender
scope(Fig.1-5)intothebracketfacingforward.
Attaching the Eyepieces:
Insertthe90°cornerlens(Fig.5-15)intothefocuserdrawtube(Fig.5-30)
andsecureintoplacebytighteningthecornerlensthumbscrew(Fig.5-32).
InsertthePlossl20mmeyepiece(Fig.5-14)intothecornerlens(Fig.5-15)
andtightendownusingtheeyepieceholderthumbscrew(Fig.5-31).

Wewillnowneedtomakethenecessaryadjustmentsinordertouseyour
telescope properly.
Balancing the Telescope:
Balancing the Mount in R.A.:
Toreducestressonthemount,thetelescopeshouldbebalancedonthepolar
axis(SeeFig.2).Instructionsonhowtodosoareasfollows:
•LoosentheR.A.lockknob(Fig.3-22)andpositionthetelescopeoff
toonesideofthemount(youmayneedtoremovetheR.A.slowmo-
tioncable(Fig.1-8)temporarily).Thecounterweightbar(Fig.1-9)
shouldbeparalleltotheground.
•Releasethetelescopegraduallyandseewhichsideitfallstowards.
Toavoidaccidentaldamage,donotletgoofthetelescopecomplete-
ly.
•Loosenthecounterweightlockknob(Fig.1-13)andpositionthe
weightsothatthetelescopeandcounterweightremainstationary
(paralleltotheoor)ontheirown.
•Tightenthecounterweightintoplace.
Balancing the Mount in Dec.:
TopreventsuddenmovementwhentheDec.lock(Fig.3-24)isloosened,the
telescopemustbebalancedonthedeclinationaxis(SeeFig.2).Instructions
onhowtodosoareasfollows:
•LoosentheR.A.lockknob(Fig.3-22)andpositionthetelescopeoff
toonesideofthemount(youmayneedtoremovetheR.A.slowmo-
tioncable(Fig.1-8)temporarily).Thecounterweightbar(Fig.1-9)
shouldbeparalleltotheground.
•TightentheR.A.lockknob(Fig.3-22)toholdthetelescopeinplace.
•LoosentheDec.lockknob(Fig.3-24)androtatethetelescopeuntil
thetubeisparallelwiththeground.
•Releasethetelescopegraduallyandseewhichwayitwillrotate.To
avoidaccidentaldamage,donotletgoofthetelescopecompletely.
•Loosenthecradleringlockknob(Fig.6-33)andslidetheoptical
tubeforwardorbackwardasneededuntilitremainsstationaryand
paralleltothegroundonitsown.
•Tightenthecradleringsecurelyaroundtheopticaltube.
•LoosentheR.A.lockknob,returnthetelescopetoitsuprightposi-
tionandretighten.
