Vulcanoid search techniques (#2)

  • Use filters to block from yellow through UV
    • Mercury-like Vulcanoids are not strong in these colors
    • Avoid solar yellow, corona green and blue sky scatter from O2

  • Image in the near-IR to Red wavelengths
    • Vulcanoids will be just below "glowing red hot"

  • Determine optimal exposure before the eclipse
    • Image stars before sunrise or after sunset
      • When Sun is 4.5 degrees to 5 degrees below the ideal horizon
