RA/Dec enables: +- CesiumJS sky layer with equatorial grid overlay +- Telescope GoTo integration (mounts speak RA/Dec) +- Cross-matching objects against star catalogs +- Proper sky chart rendering in the web UI + +### 2. Atmospheric refraction (4 functions) + +Bennett (1982) formula. Objects near the horizon appear ~0.57 deg higher than their geometric position. + +```sql +-- Basic: standard atmosphere +SELECT atmospheric_refraction(0.0); -- 0.57 deg at horizon + +-- Extended: with pressure (mbar) and temperature (C) +SELECT atmospheric_refraction_ext(0.0, 700.0, -20.0); -- high altitude, cold + +-- Apparent elevation (geometric + refraction correction) +SELECT topo_elevation_apparent(planet_observe(5, obs, NOW())); + +-- Refracted pass prediction (horizon at -0.569 deg geometric) +SELECT * FROM predict_passes_refracted( + tle, obs, start_ts, end_ts +); +``` + +**Why this matters for Craft:** +- `predict_passes_refracted()` finds passes ~35 seconds earlier/later than geometric — more accurate AOS/LOS times for rotor pre-positioning +- `topo_elevation_apparent()` gives what the observer actually *sees*, not the geometric truth +- The pass finder currently uses `predict_passes()` — drop-in replacement with `predict_passes_refracted()` for better accuracy + +### 3. Light-time corrected apparent positions (6 functions) + +Single-iteration light-time correction. Shows where an object *was* when its light left, not where it *is now*. Jupiter: ~35-52 minutes of light travel time. + +```sql +-- Planet apparent position (light-time corrected) +SELECT topo_elevation(planet_observe_apparent(5, obs, NOW())) AS jupiter_apparent; +SELECT topo_elevation(sun_observe_apparent(obs, NOW())) AS sun_apparent; + +-- Equatorial apparent (light-time corrected RA/Dec) +SELECT eq_ra(planet_equatorial_apparent(5, NOW())); +SELECT eq_ra(moon_equatorial_apparent(NOW())); + +-- Comets/asteroids +SELECT * FROM small_body_observe_apparent(oe, obs, NOW()); +SELECT eq_ra(small_body_equatorial_apparent(oe, NOW())); +``` + +**Why this matters for Craft:** The sky engine's `planet_observe()` returns geometric position. For telescope pointing accuracy, `planet_observe_apparent()` gives the correction. Matters most for outer planets. + +### 4. Stellar proper motion (2 functions) + +Stars move. Barnard's Star drifts ~10 arcseconds/year. For high-proper-motion stars, catalog J2000 coords drift noticeably over decades. + +```sql +-- Observe with proper motion (Hipparcos/Gaia convention) +SELECT topo_elevation(star_observe_pm( + ra_hours, dec_deg, + pm_ra_masyr, -- mu_alpha * cos(delta), mas/yr + pm_dec_masyr, -- mu_delta, mas/yr + parallax_mas, -- 0 to skip parallax + rv_kms, -- 0 to skip radial velocity + obs, NOW() +)); + +-- RA/Dec with proper motion +SELECT eq_ra(star_equatorial_pm( + ra_hours, dec_deg, pm_ra, pm_dec, plx, rv, NOW() +)); +``` + +**Why this matters for Craft:** If Craft's star catalog has Hipparcos/Gaia proper motion columns, these functions give positions corrected for stellar drift. The existing `star_observe()` assumes static J2000 — fine for most stars, but Barnard's Star is off by ~2.6 arcmin over 25 years. + +## Upgrade path + +### 1.

The SQL change is small: add `eq_ra(planet_equatorial(...))` to the planet CTE, `eq_ra(eci_to_equatorial(...))` to the satellite CTE, etc. + +2. **Replace `predict_passes()` with `predict_passes_refracted()`** in `pass_finder.py` — Drop-in replacement, same return signature, better AOS/LOS accuracy. + +3. **Use `planet_observe_apparent()` for telescope pointing** — When the rotor is tracking a planet, the apparent position is what the mount should point at. + +4. **Proper motion for bright star catalog** — If `star` table has Gaia/Hipparcos proper motion columns, swap `star_observe_safe()` for `star_observe_pm()` in the star CTE. + +5. **DE ephemeris RA/Dec** — If DE441 is loaded, `planet_equatorial_de()` gives sub-arcsecond RA/Dec.
