About Solar Imagimg

Chromosphere Images

Sitting about 400 km above the Photosphere is the Chromosphere.

When this layer of Hydrogen gas is excited by the radiation from the Photosphere below, the Hydrogen atoms react and they emit their own form of energy visible to us as red light.

This red energy, known as Hydrogen Alpha (Hα), is visible at a frequency of  656.28 nm  which is the bandpass that these images are captured at.

White Light or Photosphere Images

are the most popular way to observe, and image the Sun.

By reducing the overall  intensity of the disc by using special filters and prisms, we are able to see the layer at which all the visible energy of the Sun is emitted.

This layer is called the Photosphere.
