The
C90
can
be
used
without
the
45Ā®
Erect
Image
Diagonal
by
insert¬
ing
the
.96"
eyepiece
directly
into
the
rear
cell.
Keep
in
mind
that
all
images
view^
in
this
maimer
are
inverted
(i.e.,
upside
down
and
backwards).
Celestron
offers
a
wide
variety
of
eyepieces
as
optional
accessories.
To
determine
the
magnification
of
each
eyepiece
us^
with
your
C90
spotting
scope,
see
the
section
"Figuring
Magnification"
at
the
end
of
this
manual.
In
addition
to
eyepieces,
you
may
also
use
a
Barlow
lens
to
increase
magnification.
A
Barlow
lens
is
a
negative
lens
that
increases
the
focal
length
of
a
spotting
scope.
Used
with
an
eyepiece
it
will
increase
the
magnification.
The
amount
of
the
increase
is
dependent
on
the
lens
itself
and
its
position
in
the
optical
s}rstem.
Aligning
the
Finderscope
The
C90
comes
with
an
8x20
finderscope
to
help
you
locate
distant
objects
that
might
be
overlooked
in
the
narrow
field
of
the
main
optics.
The
finder
is
attached
and
aligned
at
the
Celestron
factory.
However,
if
the
finder
becomes
misaligned,
use
the
following
proce¬
dure
to
align
it:
1.
Choose
a
target
in
excess
of
one
mile
away.
This
will
eliminate
any
possible
parallax
effect.
2.
Point
the
C90
at
your
target
and
center
it
in
the
main
optics
of
the
spotting
scope.
3.
Adjust
the
screws
on
the
finderscope
bracket
until
the
ctoss
hairs
in
the
finder
are
centered
on
the
target.
4.
Tighten
each
screw
a
quarter
of
a
turn
so
they
will
not
come
loose.
Accurate
alignment
of
the
finderscope
makes
it
easy
to
find
and
center
objects
in
your
C90.
The
Optional
Lens
Shade
To
reduce
glare
and
improve
contrast
on
very
bright
days,
Celestron
offers
an
optional
lens
shade.
The
unit
threads
into
the
front
cell
of
the
standard
C90
models;
it
does
not
work
on
the
rubber
covered
models.
