Troubleshooting
Fix Blurry Planetary Photos
Learn why your planetary photos are blurry and how to fix them. Atmospheric seeing, focus issues, and processing tips explained.
Quick Solution
Use Weighted Quality Stacking stacking algorithm for the best results.
Your sharpest frames contribute most - ideal for variable seeing
Common Causes
- 1Atmospheric turbulence (seeing)
- 2Focus is not precise
- 3Motion blur from mount tracking
- 4Stacking too few frames
- 5Over-aggressive sharpening
How to Fix It
1
Use quality-weighted stacking to prioritize sharp frames
2
Stack the best frames (20-50% depending on object and conditions)
3
Capture during stable seeing conditions
4
Use a Bahtinov mask for precise focus
5
Apply wavelets gradually instead of heavy sharpening

Prevention Tips
- -Wait for nights with good seeing (twinkling stars = bad seeing)
- -Let your telescope acclimate to outside temperature
- -Capture at higher frame rates to catch moments of clarity
Why Weighted Quality Stacking?
Weighted Quality Stacking
IntermediateYour sharpest frames contribute most - ideal for variable seeing
How it works:
- 1.Measures sharpness of each frame using Laplacian variance
- 2.Sharp frames get up to 3x more weight in the final average
- 3.Blurry frames contribute less, preserving detail from good moments
Best for:
- -Nights with variable atmospheric seeing (most common scenario)
- -Capturing those brief moments of excellent clarity
- -Jupiter cloud bands and Saturn rings where micro-detail matters
