1. Plan a night

   What is up this week, from transits and variable stars to deep-sky picks. Open the sky planner

2. Keep your subs

   The single frames your Seestar can save are what measurements are made from. What your Seestar saves, and which files to keep

3. Measure or share

   See what the community's frames already show, or share a night of subs. Your targets, frame counts and hours join the sky map; nothing about where you observe is shown. See Privacy · What's in your files before you share them
