🔍 WAS JETZT FUNKTIONIERT:

ADAPTIVE Sampling basierend auf Sky Area:

area = (RA_max - RA_min) × (Dec_max - Dec_min)

if area < 100 deg²:       # Sehr nah (< 10°×10°)
    → 30,000 Sterne      # MAXIMUM Detail!
    → "🔬 Very Close"

elif area < 1,000 deg²:   # Nah (< 30°×30°)
    → 20,000 Sterne      # Hoher Detail
    → "🔍 Zoomed In"

elif area < 10,000 deg²:  # Medium (< 100°×100°)
    → 15,000 Sterne      # Medium Detail
    → "🌐 Medium View"

else:                     # Groß (zoom out)
    → 10,000 Sterne      # Overview
    → "🌌 Wide View"

📊 BEISPIELE:

Zoom IN (Detail):

RA: 260-270° (10° range)
Dec: -35 to -25° (10° range)
Area: 100 deg²
→ Zeigt 30,000 Sterne! 🔬

Zoom OUT (Overview):

RA: 0-360° (360° range)
Dec: -90 to 90° (180° range)
Area: 64,800 deg²
→ Zeigt 10,000 Sterne 🌌

Automatisch im Titel:

"🔬 Very Close - 1,234 Stars (showing 1,234)"
"🌌 Wide View - 500,000 Stars (showing 10,000)"

🎯 QUICK PRESETS:

Zoom IN Presets:

• Galactic Center: RA: 260-270°, Dec: -35 to -25°
• Orion Region: RA: 78-88°, Dec: -10 to 0°

Zoom OUT Presets:

• Northern Sky: RA: 0-360°, Dec: 0-90°
• Full Sky: RA: 0-360°, Dec: -90-90°

⚡ PERFORMANCE:

Area Size	Sample Size	Load Time	Use Case
< 100 deg²	30,000	~3s	Detail work
< 1,000 deg²	20,000	~2s	Region study
< 10,000 deg²	15,000	~2s	Large region
> 10,000 deg²	10,000	~2s	Overview

Konstant schnell, egal wie groß/klein! ⚡
