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.
