William Optics Gran Turismo GT Refractors

William Optics Gran Turismo (GT) refractors are compact apochromatic triplets for portable imaging and visual observing. The collection includes the Gran Turismo 71 APO triplet, a light travel scope, and the Gran Turismo 81 in its standard form and as the Gran Turismo WIFD 81 with internal focusing.

With a matching flattener, these small refractors suit wide nebula and galaxy fields, and they ride easily on a compact equatorial or harmonic mount.
