Re the light pollution map, I stayed for a week in a cottage in a hamlet(?) called Sheigra, sometimes Shegra, north of Kinlochbervie and then north of Oldshoremore. The coastal road north stops there. The end.
My dob and I travelled with high hopes - nay, more - this would be dark, dark, darkest black. The area is rated Bortle 1 on the map and may well be. How- e-e-ver, the half-dozen or so households in Sheigra - who leave their windows and doors unlocked 24/7 - have βsecurityβ lighting! On all night! All night!! There are camper vans, too.
And it can be cloudy. Five out of six were. A dob too far.
I have had a couple of great nights on Skye and when the skies are good they are unbeatable. Nevertheless, I think one should travel in hope but always keep expectations to a manageable level. Maps are only maps.
Just saying β¦ π
