The SARK TREK Course

Sark Trek is a two-day astronomical voyage of discovery, with approximately 14 hours of learning and stargazing activities delivered by our expert astronomers.
This course is run over the whole weekend and includes many of the things listed above as well as additional content. (A detailed schedule of the course content is available HERE. Sark Trek is a new stargazing weekend break on Sark, the world's first Dark Sky Island. It is designed to make the most of the island's incredible night skies and has been specifically created to appeal to as wide an audience as possible. No prior knowledge of astronomy is needed; we'll bring you the best of the night sky in a way that is fun and easily understandable.

Sark Trek is a collaboration between Cosmos Planetarium, Sark Astronomy Society (SAstroS) and Stocks Hotel and is part of the SAstroS Autumn Starfest.

Using state of the art technology we aim to deliver an amazing stargazing learning experience in a fantastic location. The 6 metre indoor planetarium is a fully digital, 360° immersive multi-media theatre experience, ideal for taking a journey through the solar system and learning about a range of astronomical subjects. Also on offer is the use of an array of different astronomical equipment, from simple binoculars to large astronomical telescopes with 'Goto' and wireless Bluetooth capabilities.

If you have your own telescope, bring it along and we'll show you how to get the best use from it.

During the day, we can offer solar observing with close-up views of the sun and its flares, filaments and sun-spots, using Hydrogen Alpha and white light solar telescopes.

With the planetarium, even if it's cloudy during your stay, we can still give you a virtual tour of the night sky, exactly as it should look that evening. Sark based photographer Sue Daly will also be giving a presentation on how to photograph the night sky.

To book the course only please make a cheque payable for £75 to 'Sark Astronomy Society' and post it to: Sue Daly, La Retraite, Sark, GY10 1SF.

This is an informal course and is first and foremost intended to be fun and as flexible as possible regarding the level of the content and taking weather conditions in to account. We strongly believe astronomy, and science in general, should be as accessible as possible for everyone. Lots of people get telescopes as gifts but never learn how to use them properly, feel free to bring along any equipment you have and we will endeavour to show you how to get the best out of it.

During the evening observing sessions, if the skies are clear, remember that it can be very cold so please make sure you pack appropriate clothing. To make the most of the clear skies (if we do get them!) the evening observing sessions can of course be extended. Both James and Steven are very passionate about everything to do with the night sky and will be spending a considerable amount of their nights on Sark looking up!
