 Product Description

The Parks 12.5 " f/4 & f/12 Hybrid Integrated Telescope (HIT) is really two telescopes in one: a fast f/4 Newtonian and sharp f/12 Cassegrain.

NEWTONIAN MODE

The ultra fast, rich-field (f/4) reflector mode combines large aperture and a wide field of view to deliver breathtaking views of globular clusters, open clusters, nebulae and galaxies. This mode is perfect for deep sky visual and photographic applications. Astro-photographers will appreciate the extremely fast photographic performance the f/4 design delivers.

CASSEGRAIN MODE

The long focal length (f/12) classical Cassegrain mode is ideal for high magnification, high-resolution observing and photography. The Cassegrain mode delivers stunning planetary, lunar, solar and double-star images.

MODE SWITCHING

Parks HIT Observatory systems are supplied with two secondary mirrors, 180 apart, on a rotating turret. Detents lock either mirror into alignment for desired mode. This switch can be performed in just minutes, without the need for re-collimation.

GENERAL

All mirrors are ground, polished, and hand figured completely in-house for diffraction-limited results. The optics are mounted in a genuine Parks low thermal conductive fiberglass tube. The tube provides room around the mirror for air movement without disturbing the images. A large 8x50 right angle/straight-through finderscope is standard, as is a 2" rack and pinion focuser with 1.25" adapter. The primary mirror cell and secondary mirror holder are adjustable for alignment purposes. The rotating ring system allows convenient re-positioning of the eyepiece or camera, depending on the location of the target.

New state-of-the-art, low voltage 12 VDC clock drive/drive corrector runs anywhere in the world without changing the motors or circuitry. Using less than .5 amps at 12 volts, the dual-axis drive corrector can be selected to run at lunar, solar or sidereal rates. Declination motor, declination reversing switch, and dual-axis hand control unit are included.

Also new is a spring loaded, quick release, anti-backlash declination tangent system with manual and electronic slow-motion tracking capabilities. The worm and gear are both lapped to increase accuracy, and are individually matched. A spring-loaded worm gear assembly assures 100% interfacing of the gears for superior accuracy.
