☉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.
Frame Rate
80-150 fps
Exposure
1-5ms
Gain
Low-Medium (120-250)
Sun Stacking Tutorials
Sun + Median Stacking
RecommendedBeginner
The safest choice - naturally rejects outliers and artifacts
Best for: First-time planetary photographers - safe and reliable
Sun + Weighted Quality Stacking
RecommendedIntermediate
Your sharpest frames contribute most - ideal for variable seeing
Best for: Nights with variable atmospheric seeing (most common scenario)
Sun + Sigma-Clip Stacking
RecommendedIntermediate
Statistical outlier rejection - for scientific-quality results
Best for: Removing cosmic ray hits that appear as bright dots
Sun + Local Quality Stacking
Advanced
The AutoStakkert method - 30-40% more detail possible
Best for: Maximum planetary detail extraction from good source footage
