The exoplanet search is one of the most exciting research fields in astrophysics. The Antarctic Bright Star Survey Telescope (BSST), capable of continuous exoplanet observation on polar nights, is a Ritchey–Chretien telescope with a three-lens field corrector, and has a 300 mm aperture, 2.76 focal ratio, and a wavelength coverage ranging from 0.36 to 1.014 μm. Equipped with a $4\mathrm{k}\times 4\mathrm{k}$ and $12\mathrm{\mu m}/\mathrm{pixel}$ CCD camera, the BSST can gain a field of view of 4.8°. This Letter presents the optical design, tolerance analysis, and the alignment plan for the BSST, and the test observation results.
