What is the difference between a achromatic telescope and a apochromatic telescope? - difference between achromatic or apochromatic refractor
Unfortionatly'm do not know how to tell the difference, but I looked in my books, internet, etc. I'm just a beginner.

Here is what a person had to say at a forum about the difference between the achromatic and apochromatic telescope:
"If the light through a prism of its split into its RGB components (large) when the RGB reimerges recombined back together properly (or refracted at different frequencies in different degrees) for the focal point / plane. They have different priorities and aircraft . So, if you do something by a single lens to have a rainbow around it. Or at least, red and blue halo.
An achromatic telescope has two lenses (called a doublet) is broken, at least two colors red again on the same point of focus / background, and green. Many objects are often lit with a blue halo.
The new edition (Extra Low Dispersion) telescopes a better success rate on the types of materials used in the glasses.
An apochromatic has three objectives it seeks to highlight the three colors in the same place / plane. Therefore, you do not have a halo of color. At least in the good & quot;

Hope this helps :-)
A telescope lens is adjusted so that two different wavelengths of light, are usually blue and red, the same concentration brought. This leaves the rest of the light for a Purple Haze around the sharp image to form. In an apochromatic be placed on three wavelengths of light in the same concentration, blurred to reduce the amount of light colors. Fixed an achromatic lens can be strongly influenced by a ratio of focal length, f/15 improved if the coordination relationships are so popular Anchromates classics. A Apochromat can achieve the same degree of color correction to a ratio of shorter focal length, which for a compact telescope.
Good answers above, a 20x - 30x price difference.
