CESAR team created a new Sun image.
On the image, some main features of the Sun's chromosphere such as sunspots or filaments are visible. The chromosphere is the layer above the photosphere and is thicker than it.
With a very low density, it´s impossible to observe the chromosphere without narrowband filters or during a total solar eclipse due to the brightness of the photosphere. Furthermore it’s less dense than the photosphere but reaches 25.000K at the top of the layer.
Captured with a Solarmax 90 h-Alpha telescope (9cm diameter) and a QHY5-II monochromatic camera from ESAC (European Space Astronomy Center) in Madrid, Spain.
The image is the result of stacking best 30% of the 8222 frames of a 283 seconds video. It was processed with Autostakkert 2 and Registax 6 free software.
The original image is on grayscale. The color was added later.
