Catadioptric Telescopes

Catadioptric Telescopes use a combination of both lenses and mirrors. The most common variety of "cats" would probably be the Schmidt-Cassegrains. They come in many sizes, but the 8" variety is by far the most popular. They give good views of all night sky objects. They have a vast array of accessories available. They are fairly compact and easy to use. The downside is that they are more expensive than reflectors.

• Strengths: Great for viewing all objects in the sky. They provide good aperture and magnification. They are compact and relatively easy to move about. Abundant peripherals make it easy to dabble in astrophotography or computerization. Low maintenance.
• Weaknesses: Relatively expensive.
