FAQ
Frequently Asked Questions
It is named after the Dutch mathematician, astronomer, and physicist Christiaan Huygens (1629–1695), who designed it.
It is largely obsolete in professional and high-end amateur equipment due to superior modern designs with wider fields of view and better eye relief, but it is sometimes found in simple, inexpensive instruments or discussed for educational purposes.
Advantages: Simple, inexpensive to manufacture, reduces chromatic aberration. Disadvantages: Narrow field of view, short eye relief (the distance from the lens to your eye), and it performs poorly with modern short-focus telescopes.
In British English, it's commonly pronounced /ˈhɔɪɡənz/ (HOY-guhnz). In American English, it is often pronounced /ˈhaɪɡənz/ (HY-guhnz). Both are accepted, though the Dutch original is closer to /ˈɦœyɣə(n)s/.
