The end result is that spherical aberration and field curvature are corrected to a high degree of optical performance. The VMC200L’s primary mirror is f/2.5; the compound optical system is f/9.75. This makes the system much more compact and portable than its competition. With the optical correction placed before the secondary mirror, the VMC200L avoids the necessity of having a corrector plate and all the dewing problems associated with a closed optical tube. An additional key feature is the rack and pinion focusing that is placed behind the primary mirror. The use of this focusing system eliminates the image shift associated with most other SCT systems. This is especially important when using high power magnification or astro-photography. When focusing, the image is stable and easy to adjust. Complete and Mail in the REBATE FORM.

The VMC200L on the GP2 mount is economical and versatile. The views through the VMC200L are sharper than you might expect in a mirrored optical system and the GP2 equatorial mount works smoothly and allows you to grow when you are ready by adding the Go To Starbook-S system.

Placing the optical correction placed before the secondary mirror avoids the necessity of having a corrector plate and the dewing problems associated with a closed optical tube. The rack and pinion focusing is placed behind the primary mirror. The use of this focusing system eliminates the image shift associated with most other SCT systems. This is especially important when using high power magnification or astro-photography. When focusing, the image is stable and easy to adjust. The GPD2 equatorial mount is the stronger and heftier of the GP mounts. With its solid steel R. A. and Declination axes and brass worm gears, this mount will hold up to years of heavy use. In order to assure accurate tracking for astrophotography the worm gears are especially machined to a very high precision that minimizes periodic error. Add the new Vixen Starbook S with built in star-chart for complete Go-To capabilities. VMC200L Specifications: Construction: Catadioptric reflector d=200mm (8”) f=1950mm, f/9.75 Primary mirror: f=500mm, f/2.5 Secondary mirror: d=72mm, magnification 3.9x Distance primary secondary:: ~330mm Central obstruction 80mm diameter (40% of d) Theoretical resolution (Dawes): 0.63" Theoretical min magnitude: 13.3 Tube length ~525mm incl. focuser Weight: 5.9kg Technical data GPD2 Mount * R.A Axis: 144 tooth worm gears * Declination Axis: 144 tooth worm gears * R.A. graduations: RA 10 min. increment * Dec graduations 2 deg.

The included (and upgradeable) software contains a 22,000 object database giving the user an endless variety of objects to view. Included are drop down menus of different categories of celestial objects, including Stars, Planets, Messier, NGC and other famous objects. Each sub menu only lists the objects that are available to be viewed at that time. This eliminates the frustration of other GOTO systems that don’t tell you the object is below the horizon until after you have selected it. With the Vixen Starbook you will spend more time viewing and less time searching. The package includes advanced encoded motors for accurate tracking and an auto-guider port and PEC (periodic error correction) are standard features. All of this makes the GP2 and GPD2 with STARBOOK S the most affordable, quality astro-photographer’s mount available.  | ||||

The Vixen VMC200L is a telescope suitable for observation of all types of celestial objects. It benefits from a new, lighter-weight optical tube with improved anti reflection coatings, a metal carrying handle and a 7x50 finderscope. 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 a improved SX-HAL110 heavy duty aluminum tripod. An optional illuminated polar axis scope can be easily added to the mount body. The mount utilizes the standard Vixen dovetail bracket for attachment of telescopes. Power: 12V, center pin positive. Main 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. The STARBOOK controller can be used as a stand alone star atlas from anywhere, anytime.
