Satellite Tracking and Photography Setup

Overview

  • Presenter: Dave Dickenson from Aster Guys
  • Topic: Setting up a low-cost way to track and photograph satellites

Equipment and Setup

Basic Gear

  • Homemade Weather Station: For keeping setup portable and dew-free
    • Importance: Prevents dew formation, essential for Florida climate
  • Laptop: Core of the setup, runs necessary software
    • Software: Freeware for tracking and image processing

Cooling System

  • Fan Setup: Keep area cool and maintain air circulation

Eyepiece and Webcam

  • Wide Field Eyepiece: Initial target acquisition (42mm)
  • Webcam: Logitech 4000 ($40), modified to fit eyepiece
    • Similar brightness and size to planetary bodies like Jupiter or Saturn

Tracking and Imaging Techniques

Focus and Tracking

  • Challenge: Focus and track satellites (e.g., ISS) due to rapid movement
  • Scope Details: Lacks drive motors; manual tracking required

Targeting Mechanism

  • Telrad Finder: For aiming and tracking satellites
  • Props for Manual Guide:
    • Pot grabber, broomstick, or pool stick to manually guide
    • Works similar to old-style camera guiding

Manual Tracking Demonstration

  • Method:
    • Look through reticle
    • Track satellite overhead like tracking an aircraft
    • Aim for intermittent frames: Capture 20 good frames out of 1000

Additional Tips

  • Attachment Method: Use bungees to attach guiding stick to the scope
  • Software Used:
    • K3 CCD Tools: Image processing and tracking (subscription-based)
    • RegiStax: Free image processing software

Practical Application

Focus Setup

  • Pre-Focus Tip: Use Venus for initial focus and settings (similar brightness to ISS)
  • Shutter Speed: Approximately 1/500 for capturing the ISS

Final Notes

  • Cost Efficiency: Most households already have required items (telescope, webcam, laptop)
  • Low-Tech Setup: Simple and accessible for amateur astronomers
  • Immediate Action: Can start satellite imaging the same night if setup correctly
