摘要：

We describe the balloon-borne telescope (69cm aperture) for the project Tera-GATE (THz observation with GaAs photoconductors and a balloon-borne TElescope) aiming at the THz astronomical observations. THz region is the last frontier left not well explored and we are planning to make multiband photometric observations covering the wavelength from 50 mu m to 300 mu m and get completed SED data for some Young Stellar Objects in this band. The telescope, we are constructing, has image stabilizing system which cancels out pointing error (up to about +/- 0.3 degrees) of the balloon gondola, and enables us to take a long exposure needed for highly sensitive observations. We will show characteristics of the image stabilizing system, structure of the telescope, and cold stop design.
