I live in Yokohama about 30Km(19mi) southwest of Tokyo. To watch comets, I have to drive one and half hours to Mt.Fuji about 100Km(63mi) west from there. My astro system is completely portable. The main scope is Meade 8" LX200 f/6.3 with SBIG ST-6 camera. I set up the telescope next to the car, and use an IBM compatible notebook PC to control LX200 and ST-6. The major astro software I am using are THESKY,CCDOPS, ASTROMETRICA and Brandon S. Jones' LX200 controller software.
