NPF = (35 × f-number + 30 × pixel pitch) ÷ focal length, using typical pixel pitch per format (24 MP FF, 24–26 MP APS-C, 20 MP MFT). Fine-tune for your camera with the NPF calculator.
Tips for Milky Way photography
- Shoot within a few days of the new moon, or after moonset / before moonrise.
- Use ISO 3200–6400 on modern full-frame sensors, f/1.8–f/2.8, and the NPF shutter time.
- Focus manually on a bright star with live view magnified, then lock the focus ring.
- Shoot a blue-hour or low-ISO foreground frame from the same tripod position and blend it later.
- Stack 10–20 frames to reduce noise, or use a star tracker for longer exposures.
- Check the darkest-location table above, then confirm the view to the south on the location's sun-path diagram.
