Fe XIV emission - on/off line color image
The red and blue components of this image are identical and they consist of image taken though
529.1 nm filter. This is the image of continuum only. The green component is the image taken
through 530.2 nm filter. This image is taken on the wavelength of Fe XIV emission line, however
the light contained not only Fe XIV emission but continuum as well. Both the on-line and the off-line
image were precisely calibrated and the shift of 1.1 nm between the on-line and the off-line
filter is negligible from the point of continuum intensity. Therefore the intensity of continuum in
the red, green and blue component of the image is identical and represents neutrally gray component
of the color image. The XIV emission is present only in the green component of the color image. The
image is presented in logarithm brightness scala and without any structure enhancement.

Camera | two Canon EOS 5D cameras |
Exposure | 2 s (ISO 100) - 30 s (ISO 400) |
Processing | 16 on-line and 16 off-line eclipse images used. Eclipse images calibrated by means of dark frames and flat-fields, aligned by means of phase correlation, composed by means of LDIC 5.0 software. Final processing was done using ACC 6.1 software. Image processing by Miloslav Druckmüller |
Software | Astro D3F 2.0, PhaseCorr 6.0, MPA 1.0, LDIC 5.0, Sofo ACC 6.1 |
Orientation | Image must be rotated 8.6° clockwise to achieve standard orientation i. e. North up. |
