Advanced Mode Tutorial
This guide covers manual configuration in Advanced Mode where you select the stacking algorithm and fine-tune all parameters. For automatic processing, try Quick Mode - it detects your video type and applies optimal settings automatically.
TL;DR
Want full control over your Saturn processing? Median Stacking is a Beginner-level algorithm. The safest choice - naturally rejects outliers and artifacts It works especially well for Iconic ring system with Cassini Division. This guide shows you how to configure Median Stacking in Advanced Mode for optimal results.
Introduction
Saturn is one of the most rewarding targets for amateur astrophotographers. With its Iconic ring system with Cassini Division and A, B, and C rings with varying brightness, even modest equipment can capture impressive detail. However, raw video footage straight from your camera rarely shows the full potential of your observations.
This is where Median Stacking comes in. By intelligently combining hundreds or thousands of video frames, Median Stacking For each pixel position, collects values from all frames. The result? A single image with dramatically improved detail and reduced noise.
In this guide, you'll learn exactly how to use Median Stacking to process your Saturn videos using Uranum AstroStack AI - a cloud-based tool that replaces complex desktop software like PIPP, AutoStakkert, and Registax with a simple, browser-based workflow.
Whether you're using a smartphone through an eyepiece or a dedicated planetary camera, this tutorial will help you achieve professional-quality results.
What is Median Stacking?
For each pixel, sorts all frame values and picks the middle one. Naturally eliminates extreme outliers like airplane lights, satellite trails, and sensor hot pixels. Simple but effective - a great starting point for any video.
How It Works:
- 1For each pixel position, collects values from all frames
- 2Sorts all values and selects the middle value (median)
- 3Outliers (satellites, hot pixels, cosmic rays) are naturally excluded
- 4Result is the "typical" value at each pixel - very robust
Best For:
- First-time planetary photographers - safe and reliable
- Removing satellite trails, airplane lights, Starlink streaks
- Videos with occasional bright artifacts or hot pixels
- When you are unsure which algorithm to use
Not Recommended For:
- •Videos with highly variable seeing - weighted better captures sharp moments
- •When you need maximum detail and have high-quality source footage
Why Use Median Stacking for Saturn?
Saturn presents unique challenges for astrophotographers: Dimmer than Jupiter - needs longer exposure or higher gain and Rings require precise alignment for sharp Cassini Division. Median Stacking is one of the recommended algorithms for Saturn because it effectively addresses these challenges.
Median Stacking is Recommended for Saturn
- Feature Enhancement: Saturn's Iconic ring system with Cassini Division benefit from Median Stacking's ability to First-time planetary photographers - safe and reliable.
- Challenge Mitigation: The Dimmer than Jupiter - needs longer exposure or higher gain is handled well because Median Stacking Sorts all values and selects the middle value (median).
- Skill Level: As a Beginner-level algorithm, Median Stacking is accessible even if you're new to planetary imaging.
Pro tip: For Saturn, you might also try Local Quality Stacking or Weighted Quality Stacking for comparison.
Step-by-Step Tutorial
Follow these steps to process your Saturn video using Uranum AstroStack AI. The entire process takes about 5-10 minutes.
Step 1: Capture Your Saturn Video
For best results, capture 5,000-15,000 frames at 60-100 fps. Maximum duration: 3-4 minutes (slow rotation). Use 20-40ms exposure at Medium-High (350-450) gain.
Tip: Saturn rotates slowly (10.7 hours) - you have more time than Jupiter
Step 2: Upload Your Saturn Video
Drag and drop your Saturn video file into Uranum. We support AVI, SER, MP4, MOV, and MKV formats (up to 1.5GB free, 4GB Starter, 10GB Pro).
Tip: SER format preserves maximum quality. MP4/MOV have compression artifacts but still work well.
Step 3: Select Saturn as Object Type
Choose "Saturn" from the object type dropdown. This applies optimized defaults including stack percentage (25-35%) for average seeing and enhancement settings tuned for Iconic ring system with Cassini Division.
Tip: Quick Mode will auto-detect optimal settings. Use Advanced Mode only if you need specific control.
Step 4: Choose Your Mode
Quick Mode: Automatic processing with intelligent frame selection - recommended for most users. Advanced Mode: Manual control over Median Stacking and all parameters.
Tip: Quick Mode uses knee-detection to find optimal stack percentage automatically.
Step 5: For Advanced Mode: Select Median Stacking
In the Stacking section, choose "Median Stacking". The safest choice - naturally rejects outliers and artifacts
Tip: Median Stacking is Beginner-level. First-time planetary photographers - safe and reliable.
Step 6: Set Stack Percentage Based on Seeing
Adjust based on your seeing conditions: Poor (15-20%), Average (25-35%), Good (40-50%), Excellent (55-70%). When in doubt, start with 25-35%.
Tip: Lower percentage = sharper but noisier. Higher percentage = smoother but potentially softer.
Step 7: Start Processing
Click "Start Processing". Uranum analyzes frames, ranks them by quality, stacks the best ones, and applies enhancements. Processing typically takes 2-5 minutes.
Tip: Track progress in real-time. Processing time depends on frame count and your tier.
Step 8: Download Your Result
Compare before/after using the slider. Download in PNG (8/16-bit), TIFF (16-bit), or FITS (32-bit for scientific use).
Tip: 16-bit TIFF preserves the most data for further processing in PixInsight, Photoshop, etc.
Recommended Settings for Saturn + Median Stacking
These are recommended starting values for Saturn videos with Median Stacking in Advanced Mode. Use them as a baseline and adjust based on your specific video quality and conditions.
| Setting | Value | Explanation |
|---|---|---|
| Capture Duration | 3-4 minutes (slow rotation) | Saturn has specific rotation limits. Exceeding this causes motion blur that stacking cannot fix. |
| Frame Count Target | 5,000-15,000 frames | More frames = more to choose from. Capture at 60-100 fps for optimal sampling. |
| Stack Percentage (Average Seeing) | 25-35% | For typical seeing conditions, stack 25-35% of frames. Adjust based on your seeing: poor (15-20%), average (25-35%), good (40-50%), excellent (55-70%). Quick Mode auto-detects optimal percentage. |
| Stacking Algorithm | Median Stacking | The safest choice - naturally rejects outliers and artifacts |
| Wavelet Preset | Balanced | Saturn benefits from balanced sharpening. Quick Mode auto-selects based on image sharpness analysis. |
| Output Format | 16-bit PNG or TIFF | 16-bit preserves maximum tonal information. Use for further processing in other software. |
Capture Settings Reminder
For best results with Saturn, capture at 60-100 fps with 20-40ms exposure and Medium-High (350-450) gain.
Tips for Best Results
Capture Tips for Saturn
- Saturn rotates slowly (10.7 hours) - you have more time than Jupiter
- Focus on the Cassini Division - if it is sharp, everything else will be
- Stack more frames (40%+) for better signal on the dim rings
- Use feature-aware alignment for best ring sharpness
Processing Tips
- Start with Quick Mode to see baseline results
- Use Advanced Mode to fine-tune wavelets and sharpening
- Export as 16-bit TIFF for maximum quality
- Compare different algorithms to find your preference
Common Mistakes to Avoid
- •Don't over-sharpen - it creates artifacts and noise halos
- •Don't stack 100% of frames - quality matters more than quantity
- •Don't capture during poor seeing - wait for stable air
- •Don't forget to let your telescope acclimate to outside temperature
