eastward
from
an
arbitrary
point
on
the
celestial
equator
in
the
constellation
Pisces.
The
prime
R.A.
coordinate
which
passes
through
this
point
is
designated
"O
hours
O
minutes
O
seconds".
We
call
this
reference
point
the
vernal
equinox
where
it
crosses
the
celestial
equator.
All
other
coordinates
are
names
for
the
number
of
hours,
minutes
and
seconds
that
they
lag
behind
this
coordinate
after
it
passes
overhead
moving
westward.
Given
the
celestial
coordinate
system,
it
now
becomes
possible
to
find
celestial
objects
by
translating
their
celestial
coordinates
using
telescope
pointing
positions.
For
this
you
use
setting
circles
for
R.A.
and
Dec.
to
find
celestial
coordinates
for
stellar
objects
which
are
given
in
star
charts
and
reference
books.

Polar
Alignment
To
make
tracking
the
stars
easier,
rough
polar
alignment
is
required.
1.
The
right
ascension
(polar)
axis
should
be
pointed
towards
the
North
Pole
(see
the
illustration
below).
2.
The
equatorial
mount
should
be
level.
3.
Your
latitude
should
be
set
(see
3.A).
