Tele-Station3 Roll Off Roof Observatories...packed with features not found in any other observatories available. A revolutionary, streamlined, esthetically pleasing design. Used by professional organizations such as NASA, European Space Agency, Mitre Corporation and Universities. Built to withstand harsh environmentsTele-Station 3, designed for mounting to an existing building structure. It is supplied with a short wall and brackets for mounting to your substructure perimeter ledge. If you would like to build your own substructure, but have difficulty with the roll off roof portion, this is the option for you. We will supply the roof, roll off assembly as a complete package. All you have to do is bolt it to your existing substructure. It can also be mounted to a home roof for converting a loft or attic into an observatory. It is shipped in wall and roof sections, ready for assembly. Estimated assembly time is 5 hours Included Features of the Tele-Station 3 Roll Off Roof Observatory Construction All aluminum construction with Aluminum panels making it 100% corrosion resistant and maintenance free, no painting or staining required, ever! Aluminum panels are available in 12 colors, standard. Roof is white for low heat absorption. Lockable, keeping your astronomy equipment safe. Do it yourself installation. You don't need to hire a contractor to install our observatories!! Installation is a snap due to our modular design! Wind Test: The Tele-Station3 was wind tested on November 3, 2007. This test was accomplished in another application, our Star Traveler Mobile Observatory. Both the Tele-Station3 and the Star Traveler are built with the same components and design features both on the main wall portion and roof. The Star Traveler was wind tested when it was driven from Chicago, Illinois to College Station, Texas, a trip of 1100 miles, at an average speed of 60 MPH, on an average of 6 hour intervals. Unique features of the Tele-Station3: Unlike other roll-off roof observatories, the Tele-Station 3 can be totally disassembled and re-assembled in the event that you have to relocate it! Easy installation! Walls and roof bolt together using one (1) tool, a supplied Allen wrench!!! Unique roof design. Aluminum roof comes in 5 sections, and have overlapping seams for a complete waterproof design. No permanent roller track supports, our observatories have extendable track supports that roll out with the roof making it more esthetically pleasing. The Tele-Station3 can be operated as a fully remote observatory system with the Pier-Tech 2 or Pier-Tech 3 along with our Advanced Observatory Control Software & Hardware from the comfort of your own home or from another part of the world, with our optional Wi-Fi or Cell tower communication module. With the use of our patented height adjustable pier, you can raise the telescope to view above the Tele-Station3 wall. This allows unobstructed views from the horizon to the zenith in all directions. Roll Off Roof Observatory Advantages: Unlike a dome, the Tele-Station3 does not require complex motors and electronics to move the roof as the telescope follows the sky. The Tele-Station reaches thermal equilibrium faster than a dome, and does not create a chimney effect as hot air rises out the open slit of the dome. Permits an unobstructed view of the sky for naked eye observations and wide field piggyback astrophotography. The Tele-Station3 can be dressed to match your home. Our unique aluminum framing has slots that run along the entire Tele-Station3 sidewalls allowing custom cladding to be mounted to it. Additional Features: The Tele-Station 3 can also be operated manually. Just tell us what type of telescope and mount you have, and we will take care of the rest. It can be anchored to any type of substructure.
