How I Built MoonGazers (Technical Deep Dive)
The Idea
MoonGazers had a simple goal: turn complicated forecasts into clear stargazing windows. To do that, I needed a system that could:
- Understand a user’s location.
- Gather weather + sky data.
- Score each hour of the night.
- Group good hours into 90-minute blocks.
- Return one clear answer: “Best time: 9:15 PM – 11:00 PM.”
The Stack
- Frontend: Next.js + React + Tailwind (for responsive design).
- Backend: Next.js API Routes (TypeScript).
- Data: Weather forecasts + astronomical positions (moon, planets, bright stars).
- Caching: Each dataset has its own TTL so the app is fast and reliable.
- Fallback: If one data source fails, another fills in seamlessly.
The Scoring Model
- Clouds: Clear skies get the highest weight.
- Moonlight: A bright, high moon reduces the score.
- Nighttime only: Only hours after sunset and before sunrise are considered.
- Window grouping: Adjacent “good” hours merge into 90-minute observing blocks.
This keeps the result human-friendly: instead of a wall of numbers, you get a single “best time.”
Reliability
MoonGazers uses server-side caching to reduce API calls and speed up results. If a primary data source times out, a fallback system ensures the UI still delivers a forecast in the same format.
Closing
MoonGazers isn’t just about code — it’s about design choices that make science welcoming. By combining algorithms with human-centered design, I learned how to build something both technically solid and genuinely useful.
MoonGazers User Manual (Quick Guide)
Getting Started
- Go to moongazers.prameet.space.
- Enter your ZIP code (or city if supported).
- Press Find Best Times.
What You’ll See
- Best Window → A 90-minute block when skies are clearest.
- Moon Phase → Tells you how much moonlight will affect visibility.
- Cloud Cover → Simple % so you know how clear it is.
- What’s Visible → Planets and bright stars highlighted.

Tips
- Darker locations = better results (avoid city lights).
- Refresh before you go — weather can change quickly.
- Bring binoculars if you don’t have a telescope.
