R200SS with Sphinx Mount	$3,399.00
[2742]

The remarkably fast 200mm (8") f/4 parabolic primary mirror of the R200SS Newtonian reflector gives extremely sharp images with no chromatic aberration. The use of state-of-the-art coating technology yields the ideal surface for its f/4 primary mirror. The visual observer will enjoy wide views of deep sky objects. Actual groups of nebula or clusters can be viewed at the same time with this instrument.

The telescope's large aperture and compact body make it ideally suited for astrophotography of nebulae, star clusters and comets. The use of the optional coma corrector allows for a sharp coma-free image from edge to edge, and the rack and pinion focusing mount, with an adapter, accepts 2 eyepieces.

The R200SSDG comes standard with the 7x50 finder, 232mm tube rings, dovetail tube plate and new focus design with more distance f or photographic equipment, as well as being compatible with the new Sphinx mount.

The 7x50 achromatic finder has a field of view of 6.8" and a Kellner type eyepiece

The SPHINX equatorial mount and STARBOOK controller have been intelligently engineered for high-speed automatic location of celestial objects. It is now possible to explore the beauty of the night sky with greater ease and stability. The SPHINX comes standard with built in motors and the world's first star chart go-to controller, STARBOOK, with a large full color LCD display. The Sphinx’s design is exceptional and the exterior styling is equally attractive.

Features of the SPHINX equatorial mount: 180-tooth worm gears for fine full circle motion. 22lbs. recommended loading capacity for a wide range of optical tubes. Built in DC servo motors allow for improved motion of the polar axis rotation and reduce the need for heavy counterweights.

A retractable counterweight shaft provides easy storage and transportation. The mount comes on an improved SX-HAL110 heavy duty aluminum tripod. An optional illuminated polar axis scope can be easily added to the mount body.

Features of the STAR BOOK controller: Large color liquid crystal display. (4.7 inch, 320x420 pixels, STN, 4096 colors) High Speed Internal CPU (32 bit RISC processor, 75MHz, 8MB SDRAM, 4MB Flash ROM upgradeable) Zoom-In/Out buttons for the color star chart display also control the motor speed. As you zoom in closer to an object on the display, the motor speed becomes finer and as you zoom out, the motor speed increases to cover larger distances.

Features and menu options are displayed on the large color screen and are navigated with simple buttons on the controller. The STARBOOK is easy to use and makes the SPHINX available to a wide range of ages and experience levels. A large astronomical database with 22,725 celestial objects is stored. A LAN Port within the controller allows for computer control and network connectivity. The STARBOOK is also compatible with an auto guider (including SBIG ST). The auto-guider port comes standard on all controllers.
