Femsjøen sky
A first test of the Sky-Watcher Star Adventurer tracker head. This shot is made up of 10 shots - each 2 mins at f/2,8 ISO 100 14mm. Merged using Starry Landscape Tracker then adjusted in PS (merged in one shorter exposure at the bottom to get a a sharper land silhouette. You can see that even out of town - still struggling with light pollution - far too much light in the sky. But - still fun to play with.
