SMRTR summary
Lucas Sifoni created a functional 3D-printed Dobsonian telescope that fits in a jacket pocket, built around a 76mm parabolic mirror with 300mm focal length using carbon-fiber PETG filament for structure. After refiguring the initially overcorrected mirror, the telescope achieves 0.9 Strehl performance, delivering genuine optical functionality despite its compact size.
