Description
The Sun emits light full range. Until recently, only professionals telescopes could observe the Sun in several wavelengths. Today in amateur telescopes can observe in 3 wavelengths: Cak, H-Alpha and white light. In the CaK part, you typically see brightness along the edges of large convection cells called supergranules and in areas called plages. Dark sunspots are also visible. Light from singly-ionized calcium ions in the Sun's upper photosphere and chromosphere (up to 2000 km altitude).

About Álvaro Ibáñez Pérez

I'm a spanish astrophotographer. Around 2012 I buy my first telescope (70/700 achromatic refractor) and my first Canon DSLR camera and I started taking pictures of the sky and beeing doing it ever since. Currently I have a triplet refractor 115/800 and a monochrimatic ccd. Constantly I avoid light pollution in my city, Madrid, and I have to travel more than 200km usually to take photographs of quality.
