Scotland has internationally recognised dark sky sites, which are largely protected from light pollution and recommended for stargazing.
Heymans, who lives in Edinburgh, suggests these are some of the best places to see the Northern Lights.
Galloway Forest Park, the Isle of Rum, Moffat, Tomintoul and Glenlivet in the Cairngorms, North Ronaldsay, Coll and Shetland are all designated dark sky parks.
But Heymans says Portobello Beach near Edinburgh is also a good place for urban aurora spotting as there are few streetlights and it faces north.
