My observatory
in Japanese
DOME:
A 2.5m dia. FRP Dome is set up on the roof of my house. The dome is
air conditioned throughout summer and rainy season (June to
September).
TELESCOPE:
31cm (12 inches) Newtonian reflector, fl=1525mm, F=5. The parabolic
mirror was made by I. Tasaka. The equatorial mount has been designed
and machined by S. Murasita of Uji-Tentai-Seiki (Uji=name of place
near Kyoto, Tentai=Astronomy, Seiki=Precision Instrument). The guide
telescope is a 6cm achromatic refractor loaded with ST-4, which is
worked at fl=840mm or 1680mm (depending on sky condition).
CCD CAMERA:
SBIG ST-8XME KAF1603ME/NABG 13.8mm x 13.8mm, 1534 x 1020, 16bits
Spectra-Source HPC-1 (air cooled). CCD chip: TC-215, 1k x 1k pixels, 12mm
x 12mm in size, 16 bits.
SBIG ST-7E
SBIG ST-6: my previous camera, transferred to another person at present.
SBIG ST-5 (for planets). CCD chip: TC-255, 320x240, 3.2mm x 2.4mm in
size, 14 bits.
SBIG ST-4: my first camera, used as auto guider to date. This is one
of the first lots in Japan.
SKY CONDITION:
This is Tokyo. The light pollution is always terrible. But on a nice blue
sky day, you can see Mount-Fuji in west.
