CASSINI
 

The C-90080EQ1 Astro-Terrestrial Refractor Telescope is mounted on a German Equatorial mount. The mount features solid metal construction, setting circles and locking knobs in declination and right ascension, counter balance shaft and weights, latitude adjuster, and slow motion controls with detachable flex cables in both axis. A motor drive can also be attached for added tracking capability (motor drive sold separately). The Mount is attached to a very sturdy, fully adjustable, pre-assembled metal tripod with retractable rubber feet. The telescope attaches to the EQ mount by an adjustable tube clamp which in combination with the adjustable counter balance weights ensures easy fluid movement of the telescope at all times.

The Cassini C-90080EQ1 optical tube assembly features a 900mm focal length. The objective lens is an 80mm two element achromat (color correct crown & flint) air spaced objective lens. The tube itself is aluminum, painted flat black internally, and fully baffled for excellent visual and CCD imaging. The objective is fully multi-coated and has a resolving power of 1.9 arc seconds. The optical tube assembly is diffraction limited at λ4 (1/4 wave in Sodium light). The diagonal consists of a 90° mirror, providing right-side-up images for terrestrial viewing. The finderscope is Cassini’s Mars’ Eye electronic Finderscope which helps by getting the observer behind the telescope without losing the surrounding field of view when targeting objects.

Included with the C-90080EQ1 are a 1¼″ 25mm Astroscopic eyepiece, a 1¼″ 10mm Plössl eyepiece and a 3x 2-element Barlow lens. The 25mm is a 3 element, fully color corrected, modified Rank Kasspheric eyepiece with an apparent field of view of 52°. The 10mm Plössl eyepiece is a 4 element fully color corrected eyepiece with an apparent field of view of 52°.
