#64 T-Adapter. The basic means of photography
through any ETX Astro telescope, the #64 T-Adapter
threads to the rear cell of the telescope, followed by a
T-Mount appropriate to the user’s brand of 35mm cam-
era. In this way, the cameraa body is rigidly coupled
to the telescope’s optical system, which in effect be-
comes the camera’s lens
#932 45° Erecting Prism. All ETX models include an
internal optically-at mirror to reect light to the tele-
scope’s 90° astronomical observing position. In this
position the telescope’s image is upright, but reversed.
For terrestrial observing with an ETX model, the #932
Erecting Prism correctly orients the eyepiece image
and provides a convenient 45° observing angle.
#1244 Electric Focuser. Meade-engineered for
smooth, rapid focusing with any ETX model, each
electric focuser includes coarse and micro-ne speeds.
The standard-equipment hand controller accepts one
(user-supplied) 9-volt battery and focuses the ETX
telescope. On ETX models, the focuser plugs into and
is powered by, the telescope’s control panel, with op-
eration effected through either the AutoStar or the op-
tional #497 AutoStar Computer Controller.
