Scientists have developed an impossibly thin telescope lens that addresses a key astronomical challenge in a new study funded ...

Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on ...

If your search to the best telescope for stargazing has led to a world of jargon and confusion, we're here to help. A refractor or refracting telescope uses an objective lens to collect light and ...

Well, any of us who has ever looked through a telescope could say the same, for the two principal types in use today were developed by giants: the refractor by Galileo and the reflector by Newton.

It was soon realized that what was to become known as chromatic aberration was a limiting factor in refracting telescopes, and that this could be overcome by making lenses with longer focal length ...

McKim Observatory still houses many of its original instruments, including a 9.53 inch Clark Refractor telescope, a meridian transit telescope, and a gravity driven chronograph. Missing from the early ...

The original instrument to occupy the 25-foot diameter dome was the 10.5-inch Bausch refracting telescope (f/15.5) installed in the brand new observatory in 1953. Bausch & Lomb Company gave the ...

The Beaverlab Finder TW2 is not a smart telescope, but its design makes it unique. This 82mm/3.2-inch refractor is one of a kind in that a lightweight plastic camera can be attached to it in place ...

The second floor consists of the Equatorial Room which is home to the star of McKim Observatory: a Clark Refracting Telescope with a 9.53” objective lens made by the renown Alvin Clark and Sons. The ...
