Abstract

Synoptic full-disk solar telescopes are fundamental instruments for present and future Solar Physics and Space Weather. They are typically used to study and monitor the solar activity by using high temporal cadence observations at different wavelengths. The TSST (Tor Vergata Synoptic Solar Telescope) is a new synoptic telescope composed of two spectral channels: an Hα (656.3 nm) telescope and a Magneto-Optical Filter (MOF)-based telescope in the potassium (KI D1) absorption spectral line at 769.9 nm. Hα observations are fundamental for the identification of flaring regions. The MOF-based telescope will produce line of sight magnetograms and dopplergrams of the solar photosphere, which are respectively used to study the magnetic field’s geometry in active regions and dynamics of the solar atmosphere. In this work, we present an overview on the TSST and the optical design and characteristics of the MOF-based telescope, whose optical scheme is a double-Keplerian 80 mm refractor with an aberration-free imaging lens.
