Description
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°.

Product review & video
hi my name is Mike wittmeyer and I want to thank you for purchasing your new Cassini CAT EFS electronic stabilizing reflector telescope now that sounds like a lot but it's not a lot before we go into the instructional part of this video I want to explain the telescope to you make you familiar with it explain a little bit what a reflector does and then once you have it set up you're going to be ready to use it okay this is what we call a reflector telescope it gets its name because it uses a primary mirror which is right here as you can see this after primary mirror now this is 80 millimeters in diameter which means that the mirror itself is 80 millimeters wide the wider the diameter of the mirror the more like gathering ability that you have most telescopes are in this price range give you much less aperture which is what we have what we refer to the diameter of the mirror as aperture o
