Most useful were those no longer than 30 or 40 feet—as Panek says, "long but not that long...." Goodbye to color Designers of shorter telescopes still faced the problem of chromatic aberrations ...

The drive was then on to build bigger and more powerful telescopes with greater magnification. It was soon realized that what was to become known as chromatic aberration was a limiting factor in ...

Here's how an innovative flat lens could solve these problems for satellites and space-based telescopes. Understanding Telescopes and the Limitations of Lenses . Lenses, the funda ...

larger telescopes tend to use mirrors (sometimes in combination with smaller lenses). Lenses can also suffer from a malaise known as chromatic aberration, in which different wavelengths of light ...

An affordable telescope that can easily take images ... For instance, there's Chromatic Aberration Correction to minimize color distortion (a tell-tale sign of low-cost optics) and a Motion ...

A telescope alignment method based on nodal aberration theory (NAT) is presented here to address this challenge. Without the science camera installed on the telescope, the on-axis imaging performance ...

The telescope arrived safely directly from ... which significantly reduces chromatic aberration (the color fringing around bright objects). The result is sharp images with excellent color fidelity.

Because all the colors come to focus at the same point, there is no chromatic aberration. Back when the telescope was invented by Hans Lippershey in 1608, it was done so by experimenting with ...
