This solar eclipse on August 01, 2008 in Austria was only partial with a coverage of 20.4%. All important phases could be observed on southeast sky. The over all duration in the Woodquarter region was about 01 hour and 35 minutes. The moon apparently moved from the top right through the sun disk to the left down.
The sun disk had an apparently diameter of 31.52 arcminutes and was in a distance of 151.8 million kilometers. The moon disk with a diameter of 32.9 arcminutes was a little bigger than the sun disk. The moon was in a distance of 362.600 kilometers.
In the asiatic region and in the arctic this solar eclipse was observable as a total one.

The observation in Nonndorf - Austria (48.79 North, 15.24 East)
The day started with high fog clouds dissolving only few minutes before the begin of the eclipse. So some of the last preparations and focus settings were done with some bustle. But the webcam on the modificated finder scope delivered images in the web just before the start of the eclipse for my live webcast on my new live-page www.dangl.at/live.htm.
After the first minutes the sky at last got clear and all here could observe this partial solar eclipse without problems and over full duration.
Exposures were done with the webcam (640x480) on modificated finder scope (170/50mm) and with the DSLR Canon EOS 20D (3504x2336) on Newton (1200/254mm). The exposure interval was 30 seconds on both cameras. The used mount was again the EQ6 controlled over EQMOD and Guide 8.
Visual observations of the photo sphere were done with the binocular Fujinon 16 x 70 FMT - SX and observations of the chromo sphere in h-alpha light with 656,28 nm wavelength were done with the sun telescope Coronado PST. With the PST details on the sun surface and some protuberances on the sun limb were visible clear. Both optics were mounted on a Manfrotto tripod guided manually with adjustable tilt head. Naked eye observations with eclipse glasses also showed a beautiful image from the partial covered sun.
Of course, special and safe filters were used on all optics to protect eyes and cameras.
