Night-vision (red-on-black) utilities for astrophotography and astronomy. One Launcher, six tools, all sharing a dark theme that protects dark adaptation at the telescope.

Suite-wide migration from Python 3.8 / Tkinter (and PyQt5/PyQt6) to Python 3.13
/ PySide6 (Qt6), on one consistent red-on-black night-vision design: a unified
theme, a deterministic red text caret across all input fields, per-user
writable config under Documents\\mh_astro_tools\\, wheel-safe dropdowns,
frameless title-bar chrome and a fade-from-black on launch. See RELEASE.md for
the full notes.
| Tool | Description |
|---|---|
| Suite Launcher | Opens every tool; Full and Compact modes; right-click any tool for its PDF manual. |
| Exposure Calculator | Deep-sky sub-exposure planner — AB-magnitude SNR model, field of view, pixel scale, sky-limited time, limiting magnitude. |
| UTC / GPS / Weather | Local time, UTC, exposure timer, saved GPS site, and an auto-refreshing astronomy + weather panel (sun/moon, dew, pressure, seeing, declination). |
| 500 Rule Calculator | Maximum tripod exposure before star trailing: 500 / (focal × crop). |
| Night Vision Overlay | Adjustable red screen tint — click-through, all monitors, global hotkeys, presets, region cutout. |
| Scientific Calculator | Night-vision scientific / regular calculator with DEG/RAD trig, a safe expression evaluator, and a memory panel. |
| Weather Widget | Compact desktop weather HUD with a condensation-risk readout, living in the system tray. |

All executables are code-signed by Certum with SHA-256 Authenticode and an
RFC-3161 timestamp, and are submitted to Microsoft WDSI and VirusTotal before
release. Each installed tool folder carries a signed manifest.cat and a SHA256SUMS.txt, and the installer's own SHA-256 is published above. Freshly
built Nuitka/MSVC binaries — calculation tools especially — can trigger
heuristic, reputation-based warnings in some browsers and antivirus engines;
these are not malware detections. Verify the Authenticode signature and the
published SHA-256 if in doubt.
