UsingtheTelescope:
Onceyouhaveproperlyassembledandalignedyourtelescopeyouarenally
ready to start using it.
•Tolocateanobjectusingthetelescope,rstloosenthehorizontal
lockknob(Fig.1-7)andthealtituderodcoarseadjustmentlockknob
(Fig.3-14)allowingthetelescopetorotatealongbothaxes.Look
throughthenderscope(Fig.1-1)tosighttheobjectyouarelook-
ingforandcenteritinthenderscopecross-hairs.Youmayneedto
focusthenderscopebyturningthenderscopefocusknob(Fig.
5-17).Thenre-tightenthehorizontallockknobandthealtituderod
coarseadjustmentlockknob.
•Coarsealtitudeadjustmentscanbemadebylooseningthealtitude

•Itisbesttousethelowestpowereyepiece(theHuygenian20mm
eyepiece)atrst.Thisallowsforawidereldofviewmakingit
easiertolocateobjects.Oncetheobjectiscenteredintheeldof
viewyoucanswitchtheeyepiecetohighermagnications.
•Oncetheobjectiscenteredintheeldofview,turnthefocusknobs
(Fig.1-4)ontheeyepiecefocuser(Fig.1-2)untiltheimageisclear
and sharp.
•Youwillnoticethattheviewthroughthenderscopeandtelescope
are normal, unlike other telescopes that have inverted images. This
normal view allows you to use this telescope for both terrestrial and
astronomical viewing.
•Itisbesttostartbyviewingterrestrialobjectsduringtheday.This
is a good way to practice observing with your telescope. At night it
isbesttostartbylookingatthemoonorothereasytondcelestial
objects.Asyoubecomemoreexperiencedusingyourtelescopeyou
canbegintotrylocatinghardertondobjects.
•Ifyouareviewingcelestialobjects,youwillnoticethattheobject
willslowlymoveacrosstheeldofview(causedbytherotationof
theEarth).Youwillneedtoslowlymovethetelescopevertically
and/orhorizontallytokeeptheobjectcentered.
There are many conditions that may affect your ability to focus or observe
celestialobjectsclearly.
•Brightlylitareas(lightpollution)willmakeitdifculttoseefaint
objectsinthesky.Itwillalsomakeitdifcultforyoureyestoadjust
tothedark.Youshouldtryandndadarkareaandallowyoureyes
toadjusttothedarkbeforemakingobservations.Usingared
lteredashlighttoviewchartsandyourtelescopecomponentsis
recommended to preserve your night sight. The best viewing
conditions are when the sky is inky black.
•Hazyskies,pollution,cloudsandmoisturecanallaffecttheclarity
of your viewing image.
•Avoidtouchingtheeyepieceoropticaltubewhilelookingthrough
the telescope. The vibrations caused by this contact will cause the
objectyouarelookingattomove.Youshouldalsomakesurethat
the surface you place your telescope on does not vibrate or move as
thiswillalsocauseyourviewingobjecttomove.
•Youshouldavoidsettingupyourtelescopeinsidearoomlooking
through an open window. The difference in air temperatures may
result in a blurry image.
•Viewingthroughaclosedwindowmightalsoresultinadistorted
image due to the varying densities of window glass.
•Avoidviewingobjectsthatarelowonthehorizon.Objectsthatare
higher up in the sky will appear much sharper.
•Suddenchangesintemperaturemaycausecondensationtoappear
on the optical components of the telescope. It is best to set up your
telescopeaheadoftimeandthenwaitwhilethetelescopeadjuststo
the new temperature before using it.
CareandMaintenanceofYourTelescope:
Cleaning:
•Alwaysreplacedustcoversandlenscapswhennotinuse.Thiswill
minimize the amount of dust and debris that gets into your telescope.
•Cleaningshouldbeperformedonlyifabsolutelynecessary.Ifdust
has built up on the optics use a soft camel’s hair brush or pressurized
air to gently remove it.
•Ifdewcollectsontheopticsofyourtelescopeormoisturecondenses
inside the optics, remove all accessories and place the telescope in a
dry, dust free environment and point the telescope downward.
This should help eliminate the moisture.
•Avoidtouchingthesurfaceofthemirror.
•Donotattempttotakeapartyourtelescopetocleanit.
