TS-Optics GSO 10" f/8 RC Astrograph with carbon truss tube and focuser tilting (SKU: TSRC10T)

TS-Optics GSO 10" f/8 RC Carbon Truss astrograph (TS-Optics, SKU: TSRC10T). The TSRC10T is a Ritchey–Chrétien astrograph with a 250 mm aperture and 2000 mm focal length. Its open carbon-fibre truss combines rigidity with low thermal expansion, while independent focuser tilt adjustment helps align the imaging train with the optical axis.
