Parks Optical 16" f/4 & f/15 H.I.T. OBSERVATORY SYSTEM
Parks H.I.T. Series offers today's demanding astronomers the ultimate in telescope performance and flexibility. We combine a Newtonian f/4 telescope and Classical Cassegrain f/16 telescope to produce an H.I.T. Newtonian Cassegrain telescope with 2 'mode' of operation.
The ultra fast Richfield (f/4) reflector mode, combines aperture and a wide field of view to deliver breathtaking views of globular clusters, open clusters, nebula and galaxies. This mode is perfect for deep sky visual and photographic applications. Astro-photographers will appreciate the extremely fast photographic performance an f/4 design delivers, resulting in greater productivity.
The long focal length (f/15) classical Cassegrain mode is ideal for high magnification, high-resolution photo-visual work. The Cassegrain mode will deliver stunning planetary, lunar, solar and double star images.
H.I.T. telescopes are supplied with 2 different secondary mirrors. To switch between modes the observer simply changes one secondary design for another. This switch can be performed in just a few minutes, without the need for recollimation.
