TeleVue longer, heavier 4" scopes are best matched to the rock-solid Gibraltar HD4 mount. The large bearing surfaces and thick wood legs best handle the loads, especially for high power viewing.

Leg extensions raise the altitude axis to 5-feet, still ideally sized for use with our Air-Chair observing stool. Scale on leg extensions allows repeatable setting to desired height. A wood accessory tray ties the legs together for rigidity. Built-in pier allows for high-altitude viewing. A bubble-level is integrated into the tripod base. Metal ground spikes with rubber tips are provided. 

Sky Tour Computer - Add "brains" to your TeleVue mount.

Concept: The goal of all TeleVue products is to enrich your observing experience. We view our products as a success if they cultivate your enthusiasm for amateur astronomy.

One sentiment that many TeleVue owners have expressed is their delight in owning a telescope package that is quick to set-up. So, even when there isn't the time for an extended observing session, they can still easily "just take a peek" at the sky. In other words, the equipment itself doesn't become a rationale NOT to observe.

This recurrent theme weighed strongly in shaping a computer locator. The compact size and simplicity of our Sky Tour computer belie its power and elegant functionality. It creates a unified system that is easy for every family member to carry, set-up and use successfully. We paid special attention to making Sky Tour easy to learn and giving it a sensible database. We felt it was important to include a field guide with star charts and a full listing of the objects in the computer database. With this information and the exceptional performance range of TeleVue telescopes, both novice and advanced amateurs can stretch their observing experience with every session.

Sky Tour Introduction
The Sky Tour object locator adds "brains" to your TeleVue mount. With its exclusive Lorenzin 2000+ database and refinements such as dimmable red light display, backlit button names, 10-character speed-adjustable scrolling display, and advanced "identify" capability, Sky Tour brings the hand-held computer to a new feature/performance level -- a TeleVue level of convenience and ease of use. When Sky Tour is added to TeleVue mounts, the total system is simple enough to encourage beginners, yet deep enough for experts to maintain a lifetime of observing enthusiasm.

For the amateur telescope maker, you can purchase the Sky Tour computer and encoders for integration into most any telescope mount. The Sky Tour computer can be initialized and custom calibrated for the following types of mounts: altitude-azimuth, German equatorial, fork mount, and equatorial table.

Locate 2000 Objects
More than just a star listing, Tom Lorenzin's 2000+ database is a collection of interesting and observable double and triple stars, bright and dark nebulae, galaxies, star clusters and colored stars most suited to TeleVue telescopes.

The 2000+ objects are organized into six catalogs: NGC (New General Catalog), M (Messier), IC (lndex Catalog), ST (Star), NS (Non-Standard), and PL (Planets). For quick reference, an additional FAV (Favorites) catalog is available to store 99 of your favorite objects.

Sky Tour Fun
TeleVue believes that the fun of astronomy is in the observing. Set-up and equipment operation is kept to a minimum. Sky Tour instructions are easy to follow and include step-by-step diagrams. A simple phone plug connects the computer to the TeleVue mount. Turn Sky Tour on, align the marks on the mount head, sight two known stars from a choice of 31 and Sky Tour is ready to lead you on your evening's journey outside the Solar System. If you need Sky Tour to find the planets, input the current date choose your planetary target. A little familiarity with the stars, and the alignment will take slightly longer than it did to read this paragraph!

Sky Tour's functions are organized into nine "modes." They are: Star Fix, RA DEC, Catalog, Guide, Align, Identify, Timer, Install, and Encoder. Once Sky Tour is aligned, you'll enter the Catalog mode and choose an object to view. Catalog mode displays location, brightness, size and other object information, including the chart number that contains the object in the popular Sky Atlas 2000.0 star atlas! Then switch to Guide mode to show you the direction to move the scope in order to center the selected object. Finding over 2000 objects is as simple as that!

Sky Tour also gives you digital setting circles by converting Alt/Az positioning into Right Ascension and declination. The RA DEC mode lets you hunt for any object in the sky just by looking up its RA and DEC position.

Sky Tour: the Teacher
As you scan the sky, the Identify mode will point you to the nearest object of your choosing. For example, say you wanted to know if there was a galaxy in a nearby field-of-view. Enter the Identify mode, choose "Find GX" from the nine object types. If there is a galaxy nearby, Sky Tour will identify it and guide the way. It's a wonderful way to learn about unfamiliar regions of the sky.

The Identify mode is fun for explorers who like to scan the sky just to see what they can find. When you think you've found something just ask Sky Tour's Identify mode to "Find Any "
