THE SCHMIDT 92/67 TELESCOPE: THE TELESCOPE
Characteristics
- Correcting plate: 67 cm diameter in UBK7 Schott glass
- Spherical mirror: 92 cm diameter in Duran-50 Schott glass
- Focal length: 215 cm (f/3.2, scale 95.9 arcsec/mm).
Until 1998 the telescope was used with a photographic plate of 20 x
20 cm.
The corresponding field-of-view was 5.1 x 5.1 degrees.
The telescope is equipped with a 67 cm, 4.5 degrees angle UV-transparent objective prism, with a reciprocal dispersion at H gamma of 650 Å/mm, and a 67 cm, 1 UV-transparent objective prism, with a reciprocal dispersion at H gamma of 1010 Å/mm. The two prisms can be used in direct or reversed combination.
Since December 2000 a 50'x 50' field of view CCD
camera has been implemented as a joint collaboration between the Department
of Astronomy and the Astronomical Observatory of Padova on one side, and
DLR Berlin on the other.
A filter wheel with broadband filters is foreseen for September 2001.
