¡UPDATE!: The Moon mosaic in this page has been awarded with the first prize in the Astrophotography Contest of the XIX Spanish Astronomy Conference.
After some months without taking out the 25 Obsession Telescope, we go up to the observation place called “Dornajo” in order to take some shot of Jupiter trough the webcam. The operation began at 5 in the afternoon picking up the whole necessary material distributed in several places.
After several hours, we had the 25 inches telescope mounted above the equatorial platform and polar aligned. It began what seemed a fantastic, windless and clear night. Some time later Javier Algarra arrived and also mounted their impressive Taka. While we spoke about the new astronomical gadget a bank of fog didn't allow us to see anything in the sky. The humidity also at this time overtook the saturation level soaking the whole material. After a half hour, the sky cleared up and we could begin with the planet Jupiter.
The seeing was not bad but the wind blew in gusts that made very difficult to maintain the planet inside the small ccd of the webcam. Some hours later the moon rose over the horizon and we waited to a better position close to the zenith to tray a mosaic of its surface. In order to get that we used the QHY5 CCD, but once again, the wind hinders us vastly and prevents us taking some quality videos and it didn't give us time to cover the whole surface. In spite of it, a good frame selection, the use of the appropriate software (including our new ManualFrameAlignment) and many processing hours, allowed us to obtain these results:
Remark: Even though we could have incremented the contrast in the Jupiter image, we have tried to obtain a result as close as what we really saw that night through the telescope's eyepiece.
