Advantages and Disadvantages of Reflecting Telescope
Looking for advantages and disadvantages of Reflecting Telescope?
We have collected some solid points that will help you understand the pros and cons of Reflecting Telescope in detail.
But first, let’s understand the topic:
What is Reflecting Telescope?
Reflecting Telescope is a telescope that uses a mirror to collect and focus light to form an image. It is also known as a reflector.
What are the advantages and disadvantages of Reflecting Telescope
The followings are the advantages and disadvantages of Reflecting Telescope:
|Large aperture||Susceptibility to misalignment|
|No chromatic aberration||Limited field of view|
|Low maintenance||Vulnerable to deformation|
|Affordable||Difficulty in adjusting focus|
|Compact design||Sensitive to temperature changes|
Advantages of Reflecting Telescope
- Large aperture – Reflecting telescopes, also known as reflectors, have the ability to gather large amounts of light due to their large aperture, allowing for detailed observations of celestial objects.
- No chromatic aberration – Reflectors do not suffer from chromatic aberration, a type of distortion that occurs when different wavelengths of light are focused at different points, resulting in a rainbow-like effect.
- Low maintenance – Reflectors require minimal maintenance, as the mirrors do not need to be cleaned as frequently as the lenses in refractor telescopes.
- Affordable – Reflectors are generally more affordable than refractor telescopes of the same size and quality due to the use of mirrors rather than lenses.
- Compact design – Reflectors have a more compact design compared to refractors of the same size, making them a more portable option.
Disadvantages of Reflecting Telescope
- Susceptibility to misalignment – Reflecting telescopes are more susceptible to misalignment, known as “mirror flop,” due to the movement of the primary mirror. This can affect the accuracy of observations.
- Limited field of view – Reflecting telescopes have a limited field of view due to the use of a flat secondary mirror, which can obstruct a portion of the light gathered by the primary mirror.
- Vulnerable to deformation – Reflecting telescopes are vulnerable to deformation, particularly in larger sizes, due to the weight of the mirror and its supporting structure.
- Difficulty in adjusting focus – Reflectors can be difficult to adjust the focus on, particularly for individuals with vision impairments, due to the placement of the eyepiece.
- Sensitive to temperature changes – Reflecting telescopes are sensitive to temperature changes, which can cause the mirrors to expand or contract and affect the accuracy of observations.
