Product Description
The 18mm Takahashi is a very good medium power eyepiece for lunar observing, resolving globular clusters, picking up detail in emission and reflection nebulas, etc. It provides a good 4mm exit pupil with an f/4.5 Dobsonian reflector for rich field scanning of the Milky Way star clouds in Sagittarius. It's an excellent choice to complement the 40mm eyepiece provided with some go-to Schmidt-Cassegrains. It makes an excellent all-purpose eyepiece with scopes of all optical types - refractors, Schmidt-Newtonian and Dobsonian reflectors, catadioptrics, and more.
