    The 20-foot diameter Astro Haven Enterprises enclosure is used by institutions such as Defense organizations and Universities with remote observation sites. The 20-foot model is fully automated with a digital keypad inside the dome and computer control for remote operation at any conceivable distance. 

    The quality of construction speaks to decades of aerospace engineering experience as it is capable of withstanding hurricanes or waves over the deck of a ship. This results in a lower life cycle cost for the owner as the composite construction and stainless hardware are continuously refined in response to customer feedback. Power and control are the embodiment of KISS and COTS with an elegantly simple design and factory-floor components.

    This model of 20' observatory dome from Astrohaven is a prime example of a powered clamshell dome, which uses either a 230V or 115V power source to open and close the dome. This variant includes the door option, giving a point of entry and exit, transforming this from an addition to a standing structure into a standalone observatory. The dome is primarily composed of fiberglass, and is a great choice for anyone looking to set up their own observatory. The Astrohaven 20' is an excellent investment in future astronomy success, and is professional quality on every level of performance.

    Astro Haven invented the clamshell observatory… Astro Haven Enterprises expands the envelope. In October of 2007 Astro Haven Enterprises Inc, a corporation of California took over the operations of Astro Haven Astronomical Ltd. in Canada and we are embarking on a new frontier of innovation in the areas of dome design, control and integration. In 2010 their plant in Lake Havasu City AZ was opened.

    Their new team brings years of experience in aerospace engineering, materials handling equipment design, and small business management to a product line already steeped in innovation with the mission of delivering innovative design and the best possible quality. We are dedicated to continuous improvement and their first objective was to capturing all aspects of the product in the latest in 3-D design and CAD as a foundation for future design and quality assurance.

    Astro Haven History

    In 1995 Grover Brotherston, at the age of 75 founded Astro Haven Astronomical Ltd with the idea of using fiberglass for low cost dome construction. After building a couple of rotating domes he came up with the idea of a non-rotating fiberglass clamshell design. In the thirteen years following he expanded the range of these domes from the 7-foot model up to the big 20-foot domes together with a host of variations and related products like the oval dome and the 4-foot support structure. Along the way he conceived of other applications including planetariums and concert bandstands. At the age of 88 he reluctantly passed the mantel and we are proud to inherit a great design legacy.

The "Ships Within" time frame listed with each of our products on the website applies to this time frame.
