My name is Christian Wöhler. I was born in 1970, and I grew up in Bad Salzuflen in northern Germany. With 11 years I got my first telescope, a 60 mm refractor, and became primarily interested in observing and
photographing the Moon and the planets. Later I studied physics at the University of Würzburg and obtained the Doctorate degree in computer science from the University of Bonn. Professionally, I am working as
a research scientist in the field of computer vision. Now living in Heroldstatt near Ulm in southern Germany, I am married and have two wonderful children.

In astronomy, I am focusing on high-resolution CCD imaging of the Moon and the planets. I take part in the International Outer Planets Watch and International Mars Watch observing campaigns. One of my
favourite planets is Mercury, so I also contribute to the activities of the ALPO Mercury group. With respect to the Moon,

I am concentrating on CCD imaging especially of volcanic features, lunar photometry, and
the generation of digital elevation maps. The telescope that I mainly use is a 200/1200 mm Newton; I furthermore have a 125/720 mm Newton, a 70/350 mm refractor (to obtain full-disk CCD images of the Moon
for photometrical purposes), and my old 60/700 mm refractor.
