From magnification to letting in enough light at night, here's how to choose the perfect monocular for stargazing and astronomy.

The 12x50 Monocular boasts advanced Fully Multi-Coating technology and a large BAK4 prism lens, ensuring high-contrast and color-accurate images. Whether you wear glasses or not, you can enjoy a ...

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 ...

Sir Isaac Newton once wrote, in what must be one of the most oft-quoted lines in the history of science, "If I have seen further it is by standing upon the shoulders of giants." Well, any of us ...

It is the northernmost gravitational lens known, which means there are a lot of ground-based telescopes that can conduct follow-up observations. Its peculiar nature could also be used to better ...

Telescopes don't come any smaller than the Dwarf 3, but does its portability come at the cost of image quality? Read the ...

Reflecting telescopes such as the one built by Newton in 1668 were built in part to prove his theories about chromatic aberration. Ultimately mostly correct, he proved that lenses refract light to ...

This telescope is super compact, measuring under seven inches long. It can slip into a bag or even a cup holder. It has a lens cap to keep it safe and a compass on top to make sure you don't get lost.

They used the 2.1-meter telescope there to determine that twin ... they hope to learn more about the structure of gravitational lenses and probe the mysteries of dark matter.
