Explore Scientific put their FirstLight 127mm f/9.4 Achromatic Refractor for exploring the Moon and planets within our solar system, with the capability to reach out to bright deep-sky subjects such as star clusters, galaxies, and nebulae. The refractor-style optical tube has a large 127mm (5") aperture configured with an achromatic lens system to correct chromatic and spherical aberration which translates to crisp and clear images with true color rendition with little distortion at the edges. Complementing this optical configuration, are fully multi-coated optics that increase light transmission to allow users to see distant objects better and increase details of objects within the solar system.
