Planetary images
All the planetary images presented on this page, are made with the 62cm f/15 telescope of the Observatoire de Saint Véran. The telescope is used in its prime focus and equipped with a HiSyS-22 CCD-camera. We only use a small window of the CCD-chip (KAF-400), which reduce the download- time. After careful focusing, we make a large amount of images, from which we, during the processing, only chose those images with the best seeing- conditions. The time-lap between the first and the last image chosen for the final result, has to be small enough, so that we obtain no resolution loss due to the rotation of the planet. For Jupiter, this time-lap is less than 1 minute. The exposure time is as small as possible to freeze the turbulence and sufficient large to end up with a good signal-noise relation. The pre-processing is a correction for bias and flat-field and the processing is only a unsharp mask. The tricolour images are made through R, V and B filters. The images are afterwards corrected for differences in transmit-factors of the filters and sensibility of the CCD-chip. |
