    7 1 User Manual urismo Usage he Gran Turismo 71 is designed for both daytime and nighttime viewing, as an out- standing travel scope. We recommend purchasing a WO 2” star diagonal to make the most of these little telescopes. Since the Gran Turismo 71 is well suited to viewing nebulae, clusters, large galaxies, and comets, we recommend the use of high-quality wide-angle eyepieces.
