You can select a confidently locating celestial objects. The particular object and then Argo NavisTM Argo NavisTM Digital Telescope can provide you with “guiding” information Computer (DTC) brings not only accurate that will allow you to zero-in on it by positioning information to your telescope simply manually turning the scope. but also provides an enormous detailed Alternatively, objects of interest can be database of tens of thousands of objects. reported to you on the display in real-time Stars, galaxies, galaxy clusters, as you move your scope. Argo NavisTM globular clusters, open clusters, planetary has a powerful 32-bit CPU at its heart that nebulae, nebulae, planets, asteroids, will easily allow you to continuously track comets, earth-orbiting satellites and more. satellites. The sophisticated software Magnitudes, surface brightness, object even accounts for precession, nutation sizes, common names, stellar and atmospheric refraction. A battery classifications, stellar luminosity classes, backed real-time clock provides local double star separations, variable star time, UTC time, Julian date and sidereal periods, Hubble galaxy morphologies, time. constellation, detailed parameters of The versatile and powerful tour mode planets, comets, asteroids, satellites, allows you to tailor your searches of the Moon phases and a wealth of other sky so that you may seek to find the types information are available at your fingertips of objects that interest you the most, be with a simple spin of the dial. they easy or highly challenging. A large range of mounts can Though designed for standalone use, accommodate the Argo NavisTM Argo NavisTM can also be interfaced to including Dobsonians, Forks, German your PC, laptop, tablet or smartphone Equatorials and Equatorial Tables. which brings about a wealth of additional Handheld and powered by AA features. It can operate with many of the batteries, or an optional external DC popular sky charting packages to provide you with a tracking cursor display. Using source, Argo NavisTM operates the supplied ArgonautTM utility, it even completely standalone. lets you store into its FLASH memory over After fitting a pair of optical encoders to a thousand of your own user-defined TM your mount, using the Argo Navis is objects including magnitudes and simple. Perform a quick star alignment descriptions. You can erase them and and off you go. There is no need to level store new ones as often as you like. or accurately polar align your mount.
