Alas, the Summer has now ended and the Nights begin to draw in (a bit too quickly the further north you are.....)
Every cloud has its silver lining though, the Dark nights up here in the highlands make it an excellent spot for the budding Astronomers to cast their eyes skywards (no jokes about Uranus please). We are fortunate that Light pollution is at a minimum, so seeking out those faraway Star, Galaxies, Nebula is much easier than more populated areas
Its easy to do, all you need is a decent telescope or even Binoculars and for Scotland to oblige with a cloudless Sky (Hmmm). There are readily Apps for Smartphone's that can help you navigate the Night Sky. (check out Stellar Tour - AR Stargazer)
At certain times of the year there Meteor Showers that light up the Sky, as well as occasional Visits from the Giant Snowballs or Comets as they are better know as.
Finally, the Aurora Borealis or Northern Lights can add an iridescent glow to the Northern Horizons, depending how active the Sun is.
Prepare to be amazed by the beauty of the Universe
