Checklist for Capturing Calibration Frames
- Dark Frames: Match exposure time and sensor temperature to your light frames; keep lens cap on; capture 20-30 frames.
- Flat Frames: Use uniform illumination (flat panel, twilight sky, or white T-shirt); keep focus and setup identical; aim for mid-level brightness; capture 20-50 frames.
- Bias Frames: Use shortest exposure possible with lens cap on; match ISO/gain; capture 50-100 frames.
- Organize: Label frames by type, date, exposure, and temperature to avoid confusion.
Following this checklist ensures your calibration frames will effectively clean your astrophotos and reveal stunning details.
