Record in SER format using FireCapture for 3 minutes when imaging Jupiter and 5 minutes for Saturn. Always connect your camera to USB 3 ports to achieve hundreds of frames per second, which is vital for the Lucky Imaging technique to overcome atmospheric turbulence.
After capturing, run your footage through PIPP for preprocessing—cropping empty space to improve the efficiency of subsequent stacking steps.
These initial capture and preprocessing steps are significant for successful planetary image processing.
Pre-Processing and Video Conversion
After capturing your planetary videos, you’ll need to convert them using PIPP to crop unnecessary space and set appropriate frame dimensions before stacking.
You should always choose a non-lossy codec during conversion to preserve image quality that’s essential for accurate processing.
Once converted, import your AVI files into AutoStakkert!2 where you’ll select approximately 50% of the highest quality frames to create a clean, detailed TIFF image.
Converting Video Files
Before diving into the stacking process, you’ll need to convert your raw planetary capture videos into a format that’s optimized for processing. PIPP is your go-to tool for this essential pre-processing step. When saving your files as AVI, select a non-lossy codec to maintain image quality during conversion.
Take advantage of PIPP’s cropping capabilities to eliminate empty space around your planet, setting an appropriate output frame size (around 250×250 pixels). Use the Test Options feature to preview your settings before finalizing the conversion.
Once processed, your optimized videos are ready for stacking software like AutoStakkert!2, which analyzes frame quality and generates quality graphs.
The final stacked image is typically saved as a TIFF file, perfectly prepared for further refinement in Registax.
Stacking Multiple Frames
Once you’ve captured your planetary videos, stacking multiple frames becomes the critical next step in producing sharp, detailed images.
Begin by using PIPP to preprocess your videos—crop out empty space and enhance frame size for stacking efficiency.
Convert your files to a non-lossy AVI format to preserve image quality throughout processing.
Next, import your preprocessed video into AutoStakkert and analyze it to generate a quality graph. This helps you determine how many frames to stack—generally 50% of the best frames works well before noise becomes objectionable.
As a beginner, let AutoStakkert automatically set the stacking box sizes for ideal results.
When the stacking process completes, save the image as a TIFF file in the same folder as your original video for organization and further processing.

| 3 | Select percentage | Balance detail/noise | Stack options | ~50% best frames |
| 4 | Set alignment box | Focus on details | AutoStakkert | Proper tracking |
| 5 | Save output | Preserve quality | AutoStakkert | TIFF file format |
You’ll want to stack approximately 50% of your highest-quality frames to achieve ideal balance between detail preservation and noise reduction. Most planetary cameras produce hundreds of frames, making selective stacking vital for best results.
Alignment and Stacking Techniques
After you’ve identified your best frames, proper alignment and stacking becomes the critical foundation for revealing planetary details otherwise lost in atmospheric turbulence.
AutoStakkert! excels at this process, automatically analyzing and aligning your captured frames before stacking the best ones into a single, clearer image.
For ideal results, select approximately 50% of your highest quality frames when stacking. If you’re working with individual SER files, don’t hesitate to use higher stacking percentages to maximize detail retention.
Once stacked, you’ll need to properly align your RGB channels to correct atmospheric diffraction effects that cause color fringing.
The stacking process greatly improves signal-to-noise ratio, creating a solid foundation for subsequent sharpening in software like RegiStax using wavelet processing.
Wavelet Processing for Detail Enhancement
The stacked planetary image you’ve created now holds considerably more potential detail than any single frame, but much of it remains hidden. Wavelet processing is your key to revealing these details by enhancing different spatial frequencies within your image.
| Wavelet Level | Controls | Typical Use | Best For |
|---|---|---|---|
| Layer 1 | Finest details | Increase for sharpness | Surface textures |
| Layer 2-3 | Medium details | Moderate enhancement | Cloud bands, features |
| Layer 4-6 | Large structures | Subtle adjustments | Overall structure |
| Quality/Difference Cutoff | Frame selection | Exclude poor frames | Maximizing clarity |
After applying wavelet processing, use histogram and contrast adjustments to refine your results. Remember to exclude poorly aligned quality frames using the cutoff sliders—this guarantees only the best data contributes to your final image.
Noise Reduction Strategies
Despite your careful stacking and wavelet processing, unwanted noise can still persist in your planetary images, appearing as grainy artifacts that diminish overall quality.
Apply noise reduction after stacking images and sharpening to preserve fine details. Topaz Denoise AI offers conservative noise reduction that enhances clarity without sacrificing important features.
When experimenting with settings, start with minimal adjustments—excessive noise reduction can blur essential details.
Once noise is addressed, move to color correction using tools like GIMP, Paint.NET, or Snapseed’s excellent white balance features to eliminate color casts.
Remember that each image responds differently to noise reduction techniques, so don’t hesitate to try various approaches and intensity levels until you achieve the perfect balance between noise suppression and detail preservation.
Color Balancing and Saturation Adjustments
With noise successfully minimized, your focus can now shift to refining color representation and vibrancy.
Color balancing guarantees your planetary images display natural, accurate colors by adjusting RGB components appropriately. You’ll need to apply saturation adjustments conservatively to enhance details without creating an unnatural appearance.
To achieve superior image quality:
- Use Curves layers in Photoshop or similar tools in GIMP to fine-tune specific tonal ranges, giving you precise control over color balance.
- Apply color correction tools like Snapseed to achieve proper white balance, guaranteeing colors appear true to life.
- Make saturation adjustments gradually, increasing vibrancy just enough to make details pop without over-processing.
For monochrome imaging, remember to manually align RGB color channels during processing to maintain color fidelity in your final composite images.
Sharpening Without Introducing Artifacts
Once you’ve successfully balanced colors in your planetary images, sharpening becomes your critical next step to reveal fine details while maintaining image integrity. To sharpen the image effectively, you’ll need to carefully adjust the wavelet settings in software like RegiStax, starting with moderate values and increasing gradually.
| Software | Technique | Key Consideration |
|---|---|---|
| RegiStax | Wavelet filters | Control detail at different frequencies |
| RegiStax | Quality cutoff sliders | Exclude poor quality of each frame |
| MaxIm DL | Lucy-Richardson deconvolution | Input appropriate PSF radius |
When applying sharpening, always monitor for artifacts that might appear as halos or noise. The high-pass filter in Photoshop can enhance contrast but use it sparingly to reduce noise and prevent clipping. Remember that effective sharpening enhances details without compromising the natural appearance of your planetary subject.
Finishing Touches and Final Presentation
After you’ve carefully applied sharpening techniques to bring out the details in your planetary image, your work now shifts to the final refinements that will make your image truly shine.
Use software like GIMP or Photoshop to adjust brightness and contrast, enhancing your final image’s overall appearance.
Fine-tuning brightness and contrast with professional editing software elevates your planetary image from ordinary to extraordinary.
Apply noise reduction conservatively with tools like Topaz Denoise AI—preserving details while eliminating unwanted artifacts. Consider a high-pass filter to boost contrast without compromising quality.
