Designed for serious astronomy or astrophotography, the Parks 16" f/4 Observatory telescope is equally at home in the university as it is in your backyard. It is not a high volume, assembly-line telescope. Each is custom manufactured, individually machined and hand assembled in-house. The optics, mechanics, and electronics are of unsurpassed quality.
With this remarkable system, you see not only the famed Ring Nebula (M57), but you can see the 15th magnitude central star. See the elusive Veil Nebula in Cygnus (NGC 6960), with its wispy filamentary structure and the famous Crab Nebula in Taurus (M1).
The foundation of the Observatory system is a massive, electronically controlled equatorial mount with 2" diameter stainless steel shafts. Four double-sealed, heavy-duty, precision roller bearings provide stability, accuracy, and smoothness in right-ascension and declination. Surrounding the bearings are massive aluminum housings. This equatorial head is supported on an 8" diameter steel tube pier with three heavy-duty cast aluminum legs.
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 positioning of the focuser for photographic and visual purposes.
The observatory mount is equipped with a "state-of-the-art" electronic clock drive/drive corrector. This electronic system includes: internal circuitry for dual-axis corrections; lunar, solar, and sidereal rate selections; variable speed adjustments; reversing declination switch; a built-in, 6 hour reserve power gel cell. The worm gear in the clock drive disengages for easy and precise balancing of the telescope. Spring-loaded clutch plates are adjustable.
As supplied, the telescope may be powered by either 12 VDC or 120 VAC. A cigarette plug adapter can be interfaced with either battery clip adapters or the 120-volt power supply (220-volt also available). Twelve-inch diameter, solid aluminum setting circles make the deep sky object hunt easier.
The declination axis features an exclusive tangent arm system, which allows electronic and manual slow motion tracking. Includes a spring loaded, quick release/centering device with anti-backlash.
