We no longer carry this Antares item. As an alternative, we suggest the GSO 0.965"/1.25" 45-deg Hybrid Erect Image Diagonal.
This hybrid 0.965"-1.25" prism diagonal from Antares allows you to use commonly available 1.25" size eyepieces and accessories in telescopes with a smaller 0.965" focuser. 45-degree viewing angle makes it convenient to use. Presents an erect image (right side up) so this is ideal for use with refractors for terrestrial/daytime use. Recommended for terrestrial use, although it can be used for astronomical observations as well.
