            – The Kodaikanal Solar Observatory (KoSO) is known for the discovery of the Evershed Effect in 1909.\u00a0
            – It is operated by the Indian Institute of Astrophysics (IA), and it is located in Kodaikanal, Tamil Nadu.\u00a0
            – The Kodaikanal Tower Tunnel Telescope features a sophisticated 3-mirror Coelostat system.\u00a0
            – This setup includes a primary mirror (M1) that tracks the sun, a secondary mirror (M2) that redirects sunlight downward, and a tertiary mirror (M3) that aligns the beam horizontally.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
