Nightfall Atlas

Nightfall Atlas helps astrophotographers decide what is worth imaging tonight.

Plan observing sessions around your location, gear, sky conditions, Moon phase, darkness windows, target visibility, and field risks like wind, dew, freezing temperatures, clouds, and precipitation. Build tonight or week-ahead plans, save target windows, export plan cards, add sessions to your calendar, and get native alerts when conditions or saved targets line up.

Nightfall is built for practical field decisions: what to shoot, when to start, what might get in the way, and whether tonight is worth setting up for.

Features include:
- Tonight and week-ahead astrophotography planning
- Target visibility and imaging-window recommendations
- Weather, Moon, darkness, and field-risk signals
- Saved target and saved plan reminders
- Native widgets and observing alerts
- Plan sharing and image export
- Equipment-aware planning for common astrophotography workflows

Nightfall Atlas is a planning companion for backyard and field astrophotography, built to help you spend less time guessing and more time imaging.
