Astrophotography

Several different cameras are in use with a Meade 8" LX200. The Image Gallery shows some of my results, (both good and bad!). The Tutorial provides some basic information about CCD Astrophotography and image processing.

Numerical Integration of Orbits

Experiments with numerical integration provide a simulator that shows a variety of orbital behaviour in the Solar Systems and beyond.

New Integration: Kepler 11 and KOI730.
