Wiltshire's Dark Skies Away from towns and cities, Honeystreet is the perfect place to observe the night sky far from artificial light pollution and interference.
Wiltshire Astronomical Society Founded in 1995, the Wiltshire Astronomical Society is a great way to get involved with your local astronomy community. A thriving club catering for all aspects of astronomy, from visual to imaging, radio to armchair.
Education The building of the Honeystreet Observatory will bring the awe inspiring nature of Space to visitors young and old; with a range of talks, observing nights and workshops.
The Barge Inn The observatory will be situated in the grounds of the historic canal side pub, the Barge Inn.
Possibly the only pub in the country endorsed by Camra, the Seti (Search for Extraterrestrial Intelligence) Institute and the Rolling Stones
(The Guardian)
Crop Circles The Barge indeed is Crop Circle Central theres even Croppie ale for sale and circle aficionados arrive to camp here from all over the world..."

Our Solar System

Formed some 4.6 billion years ago by the collapse of a giant molecular cloud, the planets and moons of our solar system provide some of the most spectacular images that can be seen through a telescope. From the gas giants of Jupiter and Saturn, to the rocky inner plants of Venus and Mars, each makes a fascinating target for observation.
