The society aims to educate people about Sark's skies
Sark's skies are well-known for how clear and light free they are at night.
In 2010 the island began the process of becoming the world's first Dark-Sky island and the Sark Astronomical Society was set up based on this.
Society member Annie Dachinger said: "It was surprising how many people responded [to the idea] and how many people have got telescopes."
The group hope to publish regular newsletters and hold events around happenings in the night sky.
Annie explained that living in Sark "it can be easy to take it [the clear sky] for granted because there's no direction", so the society hope to provide education on what locals can see when and promote the activity on the island.
In October 2010 Sark's status as a Dark-Sky island was yet to be confirmed but following several visits from Dark-Sky auditors, Annie explained, they were now waiting for the final decision.
Annie said: "It would bring a lot of visitors over... Sark is easy to reach and the only other Dark Sky area in the British Isles is the Galloway Forest in Scotland."
Though you can see Guernsey, Jersey, Brecqhou and France from Sark, all of which create light, none have that much effect on Sark and Annie said the island compared favourably to the Galloway Forest.
