 Product Description

The Parks 16" f/4 & f/12 Hybrid Integrated Telescope Optical Tube Assembly (OTA) is really two telescopes in one: a fast f/4 Newtonian and sharp f/12 Cassegrain.


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.


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.



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.
