Why is Local Quality Stacking good for Jupiter processing?

Local Quality Stacking is effective for Jupiter because Cloud bands with intricate detail benefit from Maximum planetary detail extraction from good source footage. Jupiter's specific challenges (Fast rotation (10-hour period) limits capture time to 60-90 seconds) make this algorithm particularly useful for extracting detail.

How does seeing affect stack percentage for Jupiter?

Stack percentage should vary with seeing conditions: In poor seeing (10-15%), be very selective. In average seeing (20-30%), use the middle range. In good seeing (35-45%), stack more frames. In excellent seeing (50-60%), you can stack the majority. Quick Mode uses intelligent knee-detection to find the optimal cutoff automatically.

How many frames should I capture for Jupiter?

For Jupiter, capture 3,000-8,000 frames at 80-150 fps. Maximum capture duration is 60-90 seconds (rotation limit) to avoid motion blur. More frames = more to choose from, better noise reduction, and more flexibility in post-processing.

What's the difference between Quick Mode and Advanced Mode?

Quick Mode automatically detects your video type (smartphone or planetary camera) and applies optimal settings including intelligent stack percentage selection - you just upload and process. Advanced Mode gives you full manual control to select Local Quality Stacking and fine-tune all parameters. Most users get excellent results with Quick Mode.

Can I use Local Quality Stacking with smartphone videos of Jupiter?

Yes, but consider that smartphone videos have compression artifacts that limit detail. Local-quality stacking is less effective with compressed video - try Median Stacking or Sigma-Clip Stacking instead. Quick Mode automatically detects smartphone video and optimizes processing for compressed footage.

How to Stack Jupiter Video with Local Quality Stacking

♃Jupiter•Advanced Level•15 min read

Learn how to stack and process Jupiter videos online. Step-by-step guide with recommended settings for cloud bands and Great Red Spot detail.

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.

Try Quick Mode

TL;DR

Want full control over your Jupiter processing? Local Quality Stacking is a Advanced-level algorithm. The AutoStakkert method - 30-40% more detail possible It works especially well for Cloud bands with intricate detail. This guide shows you how to configure Local Quality Stacking in Advanced Mode for optimal results.

Introduction

Jupiter is one of the most rewarding targets for amateur astrophotographers. With its Cloud bands with intricate detail and Great Red Spot (GRS), 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 Local Quality Stacking comes in. By intelligently combining hundreds or thousands of video frames, Local Quality Stacking Divides the image into a 6x6 grid of regions. The result? A single image with dramatically improved detail and reduced noise.

In this guide, you'll learn exactly how to use Local Quality Stacking to process your Jupiter 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 Local Quality Stacking?

Divides the image into a grid and selects the best frames independently for each region. Different parts of the frame can have their sharpest moments at different times. This "best of each region" approach can reveal 30-40% more surface detail.

How It Works:

1Divides the image into a 6x6 grid of regions
2Each region independently selects its sharpest frames
3The left side of Jupiter might use different frames than the right side
4Regions blend together with Gaussian smoothing to prevent visible boundaries

Best For:

Maximum planetary detail extraction from good source footage
Jupiter/Saturn where different regions peak at different moments
Captures with thousands of high-quality frames
Experienced imagers who want the absolute best results

Not Recommended For:

•Smartphone/compressed footage - compression limits benefit
•Short captures (<1000 frames) - not enough variation
•Poor seeing nights - there may be no good frames for some regions
•Quick processing - takes longer than global methods

Why Use Local Quality Stacking for Jupiter?

Jupiter presents unique challenges for astrophotographers: Fast rotation (10-hour period) limits capture time to 60-90 seconds and Atmospheric seeing affects cloud band detail. Local Quality Stacking is one of the recommended algorithms for Jupiter because it effectively addresses these challenges.

Local Quality Stacking is Recommended for Jupiter

Feature Enhancement: Jupiter's Cloud bands with intricate detail benefit from Local Quality Stacking's ability to Maximum planetary detail extraction from good source footage.
Challenge Mitigation: The Fast rotation (10-hour period) limits capture time to 60-90 seconds is handled well because Local Quality Stacking Each region independently selects its sharpest frames.
Skill Level: As a Advanced-level algorithm, Local Quality Stacking is suited for users who want more control over results.

Pro tip: For Jupiter, you might also try Weighted Quality Stacking or Median Stacking for comparison.

Step-by-Step Tutorial

Follow these steps to process your Jupiter video using Uranum AstroStack AI. The entire process takes about 5-10 minutes.

Step 1: Capture Your Jupiter Video

For best results, capture 3,000-8,000 frames at 80-150 fps. Maximum duration: 60-90 seconds (rotation limit). Use 8-20ms exposure at Medium (250-350) gain.

Tip: Never exceed 90 seconds - Jupiter rotates visibly even in 2 minutes

Step 2: Upload Your Jupiter Video

Drag and drop your Jupiter 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 Jupiter as Object Type

Choose "Jupiter" from the object type dropdown. This applies optimized defaults including stack percentage (20-30%) for average seeing and enhancement settings tuned for Cloud bands with intricate detail.

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 Local Quality Stacking and all parameters.

Tip: Quick Mode uses knee-detection to find optimal stack percentage automatically.

Step 5: For Advanced Mode: Select Local Quality Stacking

In the Stacking section, choose "Local Quality Stacking". The AutoStakkert method - 30-40% more detail possible

Tip: Local Quality Stacking is Advanced-level. Maximum planetary detail extraction from good source footage.

Step 6: Set Stack Percentage Based on Seeing

Adjust based on your seeing conditions: Poor (10-15%), Average (20-30%), Good (35-45%), Excellent (50-60%). When in doubt, start with 20-30%.

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 Jupiter + Local Quality Stacking
