This is a true apochromatic triplet so it may be used to Dawes limit and above when the air is steady. Extremely high spherochromatic correction snaps into focus and cuts through the seeing revealing faint planetary details during those moments of steady air. This telescope provides a perfect star test free of false color. It works equally well for visual and astro-photographic use.
