Questar Duplex is the most versatile Questar instrument because
its design permits it to be separated into two parts. The barrel,
which is actually the Field Model with moon map and star chart
added, can be carried separately in its own case for field trips.
When the two parts are assembled, the Duplex has every feature
of the fully mounted Questar Standard astronomical telescope.
To separate the barrel from the mounting, hold it in one hand,
and release the knurled screw under the collar which supports
it. The screw attaches to the ¨ù-20 hole in the bottom support
of the barrel which is used also to connect it to a tripod. The
Duplex includes lens cap, removable optical tube assembly with
mounting holes for most tripods, 16mm (80-120X) and 24mm (53-80X)
eyepieces, built-in finder (4X & 6X), Barlow lens for eyepiece
port, star-diagonal prism, 110 VAC synchronous electric drive.
Continuous 360 ¡Æ slow motion controls 25:1 with manual override
slip clutch on both axis, Declination clamp, setable right ascension
and fixed declination setting circles, finder solar filter and
carrying case. Velvet lined case has door pouches that hold one
eyepiece, 1.5" aperture solar filter, electric cord, powerguide
hand control and legs for converting to table-top polar equatorial
position. A 1/4-20 mounting hole centrally located on base can
be used to attach most tripods. 30-45 ¡Æ legs are standard. Special
order for other latitudes. Questar barrel has moon map and perpetual
star chart; the latter pulls forward to form dew cap. Weight less
than 8 lbs., in carrying case 15 lbs. Shipping weight 31 lbs.
in specially designed packing and drum. (Specify voltage and latitude).
