Sky Guide

A handy GPS-assisted sky map and recognition tool for spotting and identifying constellations, stars, planets and satellites.

Sky Safari 5 Plus

SkySafari 5 Plus is a good choice for beginners, although it will suit more serious amateurs as well.

DIY Planisphere

If you prefer a low tech approach then why not try Dominic Ford’s Planisphere.

A Planisphere is a simple hand-held device which shows a map of the stars visible in the night sky at any particular time. By rotating a wheel, it shows how stars move across the sky through the night, and how different constellations are visible at various times of year. However it will not show you where the planets are because their position is constantly changing against the night sky. For planets you would need one of the apps above.

This Planisphere is designed for use within a few degrees of latitude 55N so it will work fine in Tomintoul and Glenlivet where we are at around 57.3N.
