The concepts of a new major but medium-sized solar telescope are described. Located at one of the finest astronomical sites, La Palma, the telescope uses a doublet lens as the image forming element to minimize the number of reflecting surfaces, antireflection coatings to minimize stray light, and a separate guiding telescope outside the aperture of the telescope to avoid image degradation due to diffraction effects. Mechanically, the telescope uses the Sacramento Peak turret design which produces a minimum of local seeing effects. A short spectrograph, designed for minimum scattered light along and perpendicular to the slit, is also described. In several respects the telescope is different from other recently constructed or planned solar telescopes.
