An Astrophotographer’s Field Guide to Calibration Frames
An Astrophotographer’s Field Guide to Calibration Frames is a practical reference designed to help you understand, capture, and apply calibration frames for deep sky astrophotography using both one-shot color (OSC) and monochrome cameras.
Whether you’re just getting started or refining an advanced workflow, calibration frames are essential to producing clean, accurate, and artifact-free images. This guide walks you through how to master calibration frames — and, more importantly, how to reuse them confidently session after session.
