The 74-inch reflecting telescope at the Sutherland station of
the South African Astronomical Observatory. The telescope was
originally  at the Radcliffe Observatory outside Pretoria and
upon its closing down in the early 1970's it was moved to its
present location where it is currently the largest instrument
on site.
Although the telescope was ordered in August 1935 from Grubb,
Parsons and Co of Newcastle-upon-Tyne,  it was only completed
in 1948  owing to the intervention of World War II.       The
cylindrical  turret  covering  the  telescope  is  61 feet in
diamater and  the  mirror is  a 76-inch  disk of  pyrex  from
the Corning Glass Co.  of New York State.
The telescope is mounted on a  2 - pier asymmetrical mounting
and most  observing is done  with the  telescope  east of the
polar axis.   The newtonian focus operates at  f/4.85  with a
plate  scale  of  22.49 arc sec  per  millimetre  whilst  the
Cassegrain focus operates at f/18 with a plate scale of about
6 arc sec per millimetre.     It can also be operated at f/50
with a plate scale of about 2.2 arc sec per millimetre.
