2. Explore Scientific 80mm Air-Spaced Triplet
Explore Scientific uses special glass in its lenses that it claims to give an incredible sharpness to imagery, as well as minimising chromatic aberrations (the colour dispersion you get around especially bright objects). Despite the high quality of its parts, the ES Triplet is far from delicate. In fact, it’s made to be extremely rugged, so that astrophotographers can set up anywhere and take great pictures.
