The observatory has three Meade telescopes: two 10" Schmidt-Cassegrain
LX200 models and a 7" Maksutov-Cassegrain. These are now used as
semi-portable instruments to augment our permanently mounted C14s.
the capability of slewing automatically to any object of known co-ordinates and
centre it in the field of view.
The LX200s are capable of locating and
centring objects with a precision of better than one arcminute,
selected from a database of
more than 64,000 celestial objects.

Eyepiece Spectroscopes, 35mm camera body
Field of view:
19 x 12.6 arcmin (CCD)
computer-controlled Meade fork mount
The LX200 has a body is made of aluminium, primary and secondary mirrors of
Pyrex glass, and a correcting plate/lens of clear float glass. The
instrument as a whole weighs 86 lbs.
The Meade 7" Maksutov-Cassegrain was developed for its excellent
imaging capabilities, specifically for lunar, planetary and double-star
observations. It has a 7" spherical-meniscus correcting lens of
grade BK7 optical glass.
Imaging performance is optimised by the combination of the
spherical-meniscus lens, a strongly aspheric f/2.5 primary mirror,
and a spherical secondary mirror which multiplies the effective focal
length of the primary by a factor of six.
