ZWO ASI Cameras Planetary Photography Guide
Popular planetary cameras from ZWO including ASI290, ASI462, ASI678 - the most widely used cameras in amateur planetary imaging. Learn how to get the best results with your setup.
Typical Settings for ZWO ASI Cameras
Common capture parameters for zwo asi cameras
Frame Rate
100-200 fps (ROI dependent)
Format
SER 16-bit (via SharpCap/FireCapture)
Resolution
1936x1096 (ASI462) or 640x480 ROI for high fps
Challenges
Common issues when using zwo asi cameras
- -Many models: ASI290 (fast), ASI462 (sensitive), ASI678 (high-res) - choose based on needs
- -HCG mode (High Conversion Gain) activates at gain 80+ - changes noise characteristics
- -USB 3.0 required for full speed; USB 2.0 limits to ~40fps at full resolution
- -Amp glow visible on uncooled cameras at long exposures (>500ms)
Pro Tips
Get better results with these tips
- -Jupiter: Gain 200-250, Exposure 8-15ms, aim for histogram 70-80%
- -Saturn: Gain 270-350, Exposure 20-35ms (dimmer than Jupiter)
- -Mars: Gain 200-300, Exposure 5-12ms (varies with opposition distance)
- -HCG mode (gain 80+) reduces read noise - good for dim targets
- -Unity gain (gain 139 on ASI462MC) balances noise/dynamic range
- -Use ROI 800x600 or smaller to achieve 150+ fps for lucky imaging
Recommended Algorithms for ZWO ASI Cameras
Local Quality Stacking
Best ChoiceThe AutoStakkert method - 30-40% more detail possible
Maximum planetary detail extraction from good source footage
Weighted Quality Stacking
Your sharpest frames contribute most - ideal for variable seeing
Nights with variable atmospheric seeing (most common scenario)
Sigma-Clip Stacking
Statistical outlier rejection - for scientific-quality results
Removing cosmic ray hits that appear as bright dots
