In Memory of Didier Ledoux

Didier was one of my best friend, he was teacher for kids in Bukavu RDC. In 1987 he wrote for them a book describing the history of Earth from the origin to prehistory.

DPP Observatory is a private observatory, located in Lesve (Belgium), a small village close to Namur. Astronomy has been a hobby for over 25 years. Since 2003, I became more involved in Variable star observation. To operate a CCD camera, I decided to build a small observatory in the backyard. The fiberglass observatory dome "Home-Dome" is seated on brick and wood structure.


A custom software was designed to control the dome rotation. Now this software, named LesveDomeNet, is released as a shareware. LesveDomeNet is an cheap DIY solution to slave the dome to the telescope. It is currently used by more than 280 users all over the world. LesveDomeNet can be also used to operate a Roll Off Roof (ROR)


I also written LesvePhotometry and PeriodicVSOplanner to help Variable Star Observers.
LesvePhotometry is an automatic photometry software very useful for time-series reduction.

LesvePhotometry versions from (V retrieve UCAC4 catalog information.
