Yourtelescopealsocomeswitha3xBarlowLens(2xwith
the40AZ)whichtriplesthemagnifyingpowerofeach
eyepiece.However,thegreatlymagniedimagesshould
onlybeusedunderidealconditions–seetheCalculating

Note: Start by using a low power eyepiece as it will be
easier to focus.
Theeyepiece(orocular)isanopticalelementthatmagnies
theimagefocusedbythetelescope.Withouttheeyepiece
itwouldbeimpossibletousethetelescopevisually.
