In the doytime, oim the

Focus ihe lelescope
by rotoiing
rhe pinion knobs
llntil

in fie eyepiece ond lighten oll the clomping

Reploce rhe low

Reploce the HM]2.5MM eye
lens
with ihe
SR4MM
eye lens ond repeot the
process.
When the obidt is centered in ihe eyepiece,
recheck
ihe clomp screws for

the
odiusting screws, odiun
the linderscope so thoi lhe

done
while focused
on

providing the relescope is not
iored
severely, the
findeccope
will be occurorely
posiiioned.
ERECTING PRISM
Since the ostrononlcol
