Sun Processing Guides

Process solar videos safely online. Stack white light and H-alpha footage to reveal sunspots, granulation, and prominences.

Key Features
  • -Sunspots with umbra/penumbra structure
  • -Solar granulation (convection cells)
  • -Prominences and filaments (H-alpha)
  • -Light bridges crossing sunspot umbrae
  • -Faculae near limb brightening
Challenges
  • -CRITICAL SAFETY: Must use certified solar filter or projection
  • -Daytime seeing is typically worse than nighttime
  • -Granulation contrast is very low (~10%)
  • -H-alpha imaging requires specialized narrowband filter
Recommended Capture Settings for Sun
Solar maximum (11-year cycle) for most activity. Early morning for best seeing. Winter often has better daytime seeing.
