Plan a night under the stars, follow the sky from home or take an observing guide to sea. These tools and guides are part of Exeter Observatory.
AstroCruise: Stars at Sea
Open the cruise observing companion for ship position, local time, Moon phase, darkness and astronomical twilight, a star chart and viewing advice. Its aurora display gives a simple colour-coded guide and links to Glendale Aurora Alerts for more detail. If your device supports it, you can install the web app from your browser.
DWARF Target Finder
Find astrophotography targets for your location and sky tonight. Choose DWARF II, DWARF 3, DWARF mini or DRACO, compare imaging windows and field of view, and see scope-specific capture suggestions. You can also account for directions blocked by buildings or trees.
