# Astronomy Software & Observation Tools

Over decades of visual observing and astrophotography, I have found that the best tools are often the ones you build yourself to solve a specific problem at the eyepiece or in the workshop. Whether calculating precise ephemerides, mapping out faint deep-sky targets, or keeping an eye on local atmospheric transparency, reliable software bridges the gap between intention and execution under a dark sky.

The applications featured below are web-based utilities designed to assist observers, imagers, and star-hoppers alike. Each tool grew out of a practical need in the field—born from the desire to spend less time calculating coordinates and more time observing the universe.

Explore the individual applications below to learn more about their features and how they can support your next session under the stars.

- **[Clear Sky Alarm Clock](https://casazza.net/Home/software/./clear-sky-alarm-clock):** Monitor atmospheric conditions and transparency for upcoming observing windows.
- **[Tonight’s Sky](https://casazza.net/Home/software/./tonights-sky):** Calculate solar system ephemerides and deep-sky visual observability thresholds for your exact location.
- **[Star Hop](https://casazza.net/Home/software/./star-hop):** Generate deep-magnitude star charts tailored for visual observers hunting faint celestial objects.
- **[Astro Helper](https://casazza.net/Home/software/./astro-helper):** Traditional coordinate math and altitude-azimuth calculations built for manual and setting-circle-equipped telescopes.
