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

My name is Álvaro Ibáñez Pérez. I’m a Spanish astrophotographer, from Madrid. In 2012 I bought my first telescope (70/700 achromatic refractor) and my first Canon DSLR camera and I started taking pictures of the sky, something I’ve been doing ever since. Currently, I have a Takahashi FSQ106EDX telescope, a Takahashi EM400 mount and a monochromatic Atik 16200 CCD camera. I constantly avoid the light pollution from my city, Madrid, so I usually travel more than 200km away from home to capture quality photographs.
