What is a Cassegrain telescope?

Q: What is a Cassegrain telescope?


A: A Cassegrain telescope is a type of reflector telescope that makes use of two curved mirrors to produce an image.

Q: How does a Cassegrain telescope work?


A: The primary mirror of the Cassegrain telescope gathers and focuses light while the smaller secondary mirror reflects the light through the back of the mirror. The secondary mirror is also curved to lengthen the light path.

Q: What is a "true Cassegrain"?


A: A "true Cassegrain" is a Cassegrain telescope that uses a primary mirror with a parabola-shaped curve and a secondary mirror with a hyperbola-shaped curve.

Q: What is the advantage of using a "true Cassegrain"?


A: A "true Cassegrain" produces clear and high-quality images, perfect for serious astronomy work.

Q: Why do some Cassegrain telescopes use sphere-shaped curves?


A: Sphere-shaped curves are easier to make.

Q: What is a catadioptric telescope?


A: A catadioptric telescope is a type of telescope that makes use of both lens and mirror to produce an image.

Q: How does a catadioptric telescope fix the blurry image issue in Cassegrain telescopes?


A: A catadioptric telescope fixes the blurry image issue in Cassegrain telescopes by using a special lens in front of the telescope.
