CELESTIAL
OBSERVING
With
your
C4.5
set
up,
you
are
ready
to
use
it
for
celestial
observing.
This
section
covers
visual
observing
of
both
solar
system
and
deep-sky
objects.
Observing
the
Moon
In
the
night
sky,
the
Moon
is
a
prime
target
for
your
first
look
because
it
is
extremely
bright
and
easy
to
find.
Often,
it
is
a
temptation
to
look
at
the
Moon
when
it
is
full.
At
this
time,
the
face
we
see
is
fully
illuminated
and
its
light
can
be
overpowering.
In
addition,
little
or
no
contrast
can
be
seen
during
this
phase.
One
of
the
best
times
to
observe
the
Moon
is
during
its
partial
phases
(around
the
time
of
first
or
third
quarter).
Long
shadows
reveal
a
great
amount
of
detail
on
the
lunar
surface.
At
low
power
you
will
be
able
to
see
all
of
the
lunar
disk
at
one
time.
Change
to
higher
power
(magnification)
to
focus
in
on
a
smaller
area.
Keep
in
mind
that
if
you
are
not
using
the
clock
drive,
the
rotation
of
the
Earth
will
cause
the
Moon
to
drift
out
of
your
field
of
view.
You
will
have
to
manually
adjust
the
telescope
to
keep
the
Moon
centered.
This
effect
is
more
noticeable
at
higher
power.
If
you
are
using
the
clock
drive
and
have
polar
aligned,
the
Moon
will
remain
centered.
Consult
your
local
newspaper
or
a
current
astronomy
magazine
to
find
out
when
the
Moon
is
visible.
Try
using
filters
to
increase
contrast
and
bring
out
more
detail
on
the
lunar
surface.
Observing
the
Planets
Other
easy
targets
in
the
night
sky
include
the
five
naked
eye
planets.
You
can
see
Venus
go
through
its
lunar-like
phases.
Mars
can
reveal
a
host
of
surface
detail
and
one,
if
not
both,
of
its
polar
caps.
You
will
be
able
to
see
the
cloud
belts
of
Jupiter
and
the
great
Red
Spot
(if
it
is
visible
at
the
time
you
are
observing).
In
addition,
you
will
also
be
able
to
see
the
moons
of
Jupiter
as
they
orbit
this
gas
giant.
Saturn
with
its
beautiful
ring
system
and
Cassini's
division
are
easily
visible
at
moderate
power.
All
you
need
to
know
is
where
to
look.
Most
astronomy
publications
tell
where
the
planets
can
be
found
in
the
sky
each
month.
Figure
6-1
This
scanned
drawing
of
Jupiter
provides
a
good
representation
of
what
you
can
expect
to
see
with
moderate
magnification
during
good
seeing
conditions.
The
large,
bright
cloud
belts
should
be
immediately
obvious.
Smaller,
faint
belts
become
visible
with
practice
and
experience.
