Add 10micron Park Position Monitor

[d33psky]

Summary

• New monitoring system for 10micron mount parking position accuracy
• Automatically detects and corrects position drift
• Comprehensive monitoring with dual connection architecture (INDI + Mount API)

Key Features

• Position Drift Detection: Compares actual vs expected park position with configurable tolerance
• Automated Correction: First attempts INDI park command, then mount API as fallback
• Ultra Precision Mode: Uses mount's #:U2# mode for high-precision coordinates
• Persistent Connections: Long-lived TCP connections with threading for reliability
• Comprehensive Logging: ISO8601 timestamped logs for all operations
• Mattermost Alerting: Sends alerts when corrections fail

Implementation Details

• Main loop runs every 60 seconds
• Monitors both INDI server (192.168.100.14:7624) and Mount API (192.168.100.73:3490)
• Handles coordinate parsing in HH:MM:SS.SS and +DD:MM:SS.SS formats
• Uses existing Mattermost integration pattern from other observatory components
• Configurable park position and drift tolerance via YAML

Test Results

✅ Successfully connects to both INDI and Mount API
✅ Ultra Precision Mode working - coordinates in HH:MM:SS format
✅ Position drift detection working with 0.126° tolerance
✅ Mattermost alerts working
✅ No datetime deprecation warnings

Current mount position: RA 18:32:46.55, DEC +40:04:55.3 (within tolerance)

🔧 Fixed Sidereal Time Drift Issue

Problem Identified: The original implementation used RA/DEC coordinates which naturally drift with Earth's rotation (~1 minute per minute), causing false drift detection.

Solution Implemented: Switched to ALT/AZ coordinates which are fixed to the local horizon and remain constant when mount is parked.

✅ Updated Implementation:

• Mount API Commands: Now uses #:GA# (altitude) and #:GZ# (azimuth)
• Configuration: Updated with actual park position (ALT: 1.982°, AZ: 359.747°)
• Ultra Precision: Parsing coordinates in DD:MM:SS.SS format
• Enhanced Logging: Added blank lines between cycles for readability

📊 Test Results:

• ALT drift: 0.0001° (0.36 arcseconds)
• AZ drift: 0.0009° (3.2 arcseconds)
• Total drift: 0.0009° - well within 1.0° tolerance

The program now correctly detects actual mechanical drift rather than normal celestial motion. Ready for production monitoring! 🚀
