SkyWindow helps amateur astronomers plan what they can actually see from their location on any given night.
• Capture and analyze your horizon profile with your phone camera
• Get a personalized target list filtered by your horizon, light pollution (Bortle zone), moon phase, and weather
• Plan observing sessions with an interactive night planner
• Save equipment profiles (including smart telescope presets)
• Log your observing sessions and track what you've seen
Whether you're setting up a visual telescope or a smart scope, SkyWindow shows you what's worth observing tonight — and what isn't.
