Photography tips
How this image was taken
This night shot combines an open aperture of f/2 and a moderate shutter speed of 7.7 seconds to capture both the starry sky and the faint red light on the telescope. The ISO 1600 provides the necessary light sensitivity for this 12 mm wide-angle exposure.
- Use an open aperture like f/2 to allow as much light as possible to reach the sensor in low light conditions.
- Select a short shutter speed to keep the stars sharp and avoid motion blur caused by the rotation of the earth.
- Use a wide-angle lens to capture both the subject at the telescope and the vast starry sky in one frame.
