However, using only a solar filter and camera results in a very small image of the Sun's disk, even with zoom lenses of 200mm to 300mm focal length (35mm equivalent). You can manually hold these simple filters in front of a smartphone or point-and-shoot while imaging. Filters such as solar eclipse cards or eclipse glasses reduce the intensity of the Sun's light by a factor of 100,000 or more, but they still give a sufficiently bright image for the camera's sensor. In this article, you get a few tips and suggestions to get you started imaging the Sun with white-light solar filters and narrow-band solar filters such as H-alpha and Ca-K.ĩ.2 Imaging the Sun with a Smartphone or Point-and-Shoot CameraĪiming an unfiltered camera at the Sun for any length of time may cause damage to the sensor, so it's essential to have a solar filter in front of the camera to completely cover the lens and keep the light to a safe level for the camera sensor and your eye. Eventually, however, there comes a time when you wish to record your observations by capturing images of the Sun. And special events such as planetary transits or total and partial solar eclipses add to the pleasure of amateur solar astronomy. Features like sunspots, solar flares and prominences, faculae and tiny spicules are fascinating to watch. Visual observation of the Sun, whether in white-light or in narrow band like H-alpha, rewards the observer with ever changing and close-up views of a major star in action.
