Zone Science How much does a telescope cost
Welcome to how much does a telescope cost. This can depend on a lot of things...
Here we will go through the different types of telescopes.
Three basic telescope designs use different optics to achieve the same result. These can make distant objects look bigger and brighter than they appear to your eye. See the text for links to animations that show how light passes through the optics of each design.
• Refractors have a lens at the front of the tube. These are the type you're probably most familiar with. While generally low maintenance, they quickly get expensive as the aperture increases. In refractor lingo, an apochromat offers better optical quality, but is more expensive, than an achromat of the same size.
• Reflectors gather light using a mirror at the rear of the main tube. For a given aperture, these are generally the least expensive type, but you'll need to adjust the optical alignment every now and then. More often if you bump it around a lot but that adjustment, called collimation, is straightforward.
• Compound (or catadioptric) telescopes, which use a combination of lenses and mirrors, offer compact tubes and relatively light weight. Two popular designs you'll often see are called Schmidt-Cassegrains and Maksutov-Cassegrains.
So that covers the technical part on the three types of telescopes.
How do you decide which one is right for you?
- I'd like a telescope for a beginner - Refractor or Reflector.
- I'd like a telescope that requires little or no maintenance - Refractor.
- I'd like to also observe objects close by like wildlife - Refractor or Compound.
- I'd like to view faint, deep sky objects: Reflector or Compound.
- I'd like the best image quality: Reflector or Compound.
- I'd like the biggest bang for my buck (high value): Reflector.
