Sunrise is a bi-national US-German program for spectro-polarimetric high-resolution observations of the sun. The ob-servations will be done by a balloon telescope circulating in high altitudes around Antarctica. The paper describes de-sign concepts for the telescope in the balloon gondola. The designs are driven by the environment of the balloon (which is something between earthbound and space). Main design drivers for the telescope are light-weighting, thermal treat-ment of looking to the sun, stability and alignment of the optical elements during operation and handling and safety issues during lift-off and landing. The achievable weight and performance data are demonstrated by structural and ther-mal analyses results.
