The latest creation from Astro Haven is their five-shutter 18" clamshell observatory. The 18' model, with its innovative 5 shutter design, provides maximum height from the base to the top while still providing a great low elevation view. There is room in the Astro Haven 18' Dome for several piers and large telescopes, and it will accommodate large groups of visitors. Astro Haven clamshell domes are currently operating at the North Pole as well as the highest elevations of Peru, which should be proof of its ability to operate in the harshest of climates.
Built Tough to Last with Minimal Maintenance
This super tough non-rotating 18" clamshell dome is constructed of fiberglass using closed mold vacuum techniques. Decades of aerospace engineering experience has been applied to its fabrication and design. The exterior is white gel coated for great UV protection. For those who would like to match their dome to an existing building or to the dome's surroundings, a color matching option is available.
Clamshell vs Rotating Dome
Unlike traditional rotating domes, an Astro Haven clamshell-style observatory allows the user to choose how much exposure they desire. Operate wide open to have an unobstructed view of the sky, which is the perfect way to achieve immediate thermal equilibrium, or enjoy a beautiful summer night out under the celestial canopy. Partial closure offers protection against wind and shields against the light coming from a particular direction. When fully closed, your dome is sealed up tight, offering protection against most any weather Mother Nature can throw at it.
Mount on a Foundation or Building
The height of the Astro Haven 18" Dome is 14' 2". Customers either add the dome to the top of a structure and add stairs to reach the equipment, or they lay a foundation and simply bolt the Astro Haven dome down. Entry to the dome can be achieved by adding an optional access hatch with an automotive type slam lock (choose in the Options drop-down).
Electronic Opening System
The Astro Haven 16" Clamshell Dome includes a 230V shutter opening system with a digital keypad inside the dome and a computer interface for remote operation from your living room, classroom, or any other location in the world. If you will be operating in a very humid environment, Astro Haven offers a watertight NEMA 4 option for the motor assemblies. You can also choose to add a non-metallic trim kit to your dome that will be optimum for humid or corrosive environments.
When your Astro Haven dome is ready, it can either be picked up at the factory or you can have it crated and shipped to your destination. Crating and handling are extra. If you live outside the USA, treated wood is required for shipment. In this instance, choose the International Crating option as opposed to the USA Crating option. The Astro Haven 18-Ft. Dome weights about 2200 lb. It ships in 14 pieces and comes on two skids that weigh about 700 lb. each and are 72" high x 90" wide x 192" long. Obviously, this is not going via UPS or USPS! OPT will contact you when your dome is ready and a shipping quote will be generated at that time.
When your dome arrives, it is easy to install in about a day by assembling the pieces and bolting the lower flange of the dome to a concrete pad or structure that is isolated from your pier. Bolts need to be inserted every 24'. For those rare occasions when that is not an option, Astro Haven offers Base-Hold Down Plates, which are sold separately.
Freight cost will be calculated at time of shipment. A forklift will be needed for off-loading at the customer’s expense.
