Preparing Your Data for PixInsight

Introduction

Getting the most from PixInsight starts before you even launch the software. Proper organisation and well-prepared calibration data set the foundation for a smooth workflow and better results.

This guide focuses on structuring your data, preparing calibration frames, and getting everything ready for processing.

Why Preparation Matters

Astrophotography sessions generate large numbers of files. Without organisation, it’s easy to misplace data or mismatch calibration frames.

A consistent workflow saves time and prevents errors later.

Organising Your Data

Use a dedicated folder for each target and date. Inside, create subfolders for each frame type:

Use consistent file naming:

• Light_001.CR2
• Dark_001.CR2
• Flat_001.CR2

Consistency makes processing and revisiting data much easier.

Preparing Calibration Frames

• Darks: Remove thermal noise and hot pixels
• Flats: Correct vignetting and dust
• Bias: Capture read noise
• Dark Flats: Used instead of bias for flats

Keep calibration frames organised and clearly labelled for each session.

Backups and Archiving

Always keep raw data untouched. Store master calibration files in a dedicated folder.

A simple backup system ensures your work is safe and can be reprocessed later.

Summary of Preparation Steps

Next Steps

Once your data is organised and calibrated, you can move on to evaluation and stacking.

Next: screening subframes, stacking workflows, and image processing.
