The members of KNVWS 't Gooi
Our members are interested in a variety of theoretical and practical aspects of astronomy and meteorology. Some of their pages, such as Ruud Zappeij's own observatory and the beautiful eclipse photos from Hans Keuning, are in Dutch (but still worth looking at, since a picture is worth a 1000 words...). Because of their international work, some members' pages, including Günther Können's articles on atmospheric phenomena, and astrophotography by Lynn van Rooijen are also in English.
Hans Keuning
Hans is a member of the KNVWS, treasurer of KNVWS 't Gooi en coordinator of the Workgroup Practical Astronomy (WPS). He was the initiator of our star parties many years ago.
Hans has experience with both observational astronomy and eclipse photography. On his pages, you will find beautiful examples of Lunar eclipses and the total Solar eclipse of 2006 in Turkey. (read more...)
Günther Können
Günther Können (1944) has been a member of the KNVWS since 1964 as well as board member of the Amsterdam Chapter and Chariman of the Workgroup Meteors. Hij has many areas of interest, ranging from space missions to astronomy, physics, celestial mechanics and meteorological optics, including polarisation. Most of his time is devoted to theoretical studies of halos over which he writes both popular and professional articles. A selection of his recent work can be found on his pages. (read more...)
Lynn van Rooijen
Lynn is charman of KNVWS 't Gooi. She has been interested in astronomy since childhood, but has only been active as an amateur for the last 12 years. She recently completed a MSc (Astronomy) degree. Lynn gives presentations for schools and clubs, and is the NASA-JPL "Solar System Ambassador" voor de Benelux. Her particular interests are exoplanets and astrophotography. You can find some of her astrophotography on the her pages, as well as more information on the Solar System Ambassador program. (read more...)
Ruud Zappeij
Ruud (1943) was also interested in astronomy since childhood, but his interest took on serious proportions after a comet crashed on Jupiter in 1994. He subsequently completed an intensive 6-week astronomy course "down under".
In 1999, Ruud buit his own observatory on his roof. After his retirement in 2003, he became a member of the KNVWS 't Gooi. (read more...)
