Stacking and Integrating Multi-Year Datasets in Astro Pixel Processor
In this tutorial, Telescope Live tutor Nik Szymanek demonstrates how to combine astrophotography datasets taken years apart with different cameras using Astro Pixel Processor (APP). This method enables seamless integration of large datasets while maintaining high image quality. Key steps include:
Loading and Organizing Data:
- Import and analyze datasets captured with an FLI PL9000 CCD and a QHY 600M CMOS camera.
- Understand how APP handles different sensor sizes and orientations.
Calibration and Registration:
- Use APP’s Analyze Stars tool to assess sub-exposure quality and remove outliers.
- Fine-tune registration settings to align frames from different imaging sessions.
Stacking and Color Combination:
- Normalize images to correct background variations across multiple nights.
- Use Multiband Blending (MBB) and RGB integration tools to generate the final color image.
This tutorial provides a step-by-step workflow for integrating diverse imaging data into a high-quality astrophotography result.

Streamlining Data Stacking with Fast Batch Pre-Processing
In this tutorial, Alexander Curry, Co-Founder of Telescope Live, introduces the Fast Batch Pre-Processing (FBPP) script in PixInsight, designed to speed up the data stacking process while maintaining high-quality results. Key points include:
FBPP vs. Weighted Batch Pre-Processing (WBPP):
- Learn how FBPP reduces processing times significantly—handling large datasets in minutes compared to hours with WBPP.
Simplified Workflow:
- Explore how to efficiently configure FBPP for bias, dark, and flat frames. Understand grouping keywords and automatic integration options for seamless stacking.
Comparison of Outputs:
- See a direct comparison between FBPP and WBPP results, including master frame quality, noise levels, and processing differences.
[Free] Mastering the Cosmic Clarity Suite: Sharpening and Denoising Tools
In this free intermediate tutorial, Alexander Curry, Co-Founder of Telescope Live, explores the powerful tools in the Cosmic Clarity Suite, including AI based sharpening and denoising features designed for astrophotography. This free tutorial and software provided by Seti Astro are an excellent alternative to the Xterminator plugins. Key topics include:
Denoising for Enhanced Image Clarity:
- Learn how to apply the denoising tool to smooth out graininess in images.
- Adjust denoising strength to preserve fine details, especially for high SNR datasets.
Advanced Sharpening Techniques:
- Use the sharpening tool for both stellar and non-stellar regions.
- Understand how to calculate and input PSF values manually for improved accuracy.
- Fine-tune sharpening levels to avoid over-enhancing stars or increasing noise.
Optimized Workflow and Compatibility:
- Discover how to integrate these tools with any post-processing software or workflow.
This tutorial provides practical insights into leveraging the Cosmic Clarity Suite to achieve sharper, cleaner astrophotography results.
