Types of Telescopes
Refracting Telescopes (Refractors)
- Overview:
In case of Refracting telescopes lenses are used to collect and focus the light. This type of telescopes have an iconic design, with a long tube and a convex objective lens at the front, basically it is used for stargazing. - Use:
Planetary Observation:
With the help of a refracting telescope, the planets in the planetary system can be visible clearly, we can see scenes like the cloud bands of Jupiter and the rings of Saturn.
It is used to view complex features of the Moon’s surface.
Reflecting Telescopes (Reflectors)
- Overview:
In case of Reflector telescopes mirrors are used to collect and reflect light. The primary mirror captures the incoming light and passes it to the secondary mirror, which then passes it to the eyepiece. The primary mirror is often parabolic in shape. - Use:
Deep-Sky Observation:
Reflector telescopes are used to discover faint and distant objects such as galaxies, nebulae and star clusters. Due to their larger aperture they become powerful instruments by capturing more light.
Astrophotography:
Reflectors are widely used for astrophotography due to their ability to gather light effectively. They are popular choices for capturing detailed images of celestial wonders.
Compound Telescopes (Catadioptric Telescopes)
- Overview:
In case of Compound telescopes both mirror and lenses are used , due to this it provides the advantages of both refractor telescope and reflector telescope. - Use:
Versatility:
Compound telescopes are versatile and suitable for various types of observation, making them popular choices for amateur astronomers seeking a well-rounded instrument.
Portability:
Their compact design and portability make them convenient for stargazing sessions in different locations.
Dobsonian Telescopes
- Overview:
Dobsonian telescopes are a type of reflecting telescope known for their simplicity and large apertures. They consist of a primary mirror on a simple, sturdy mount. - Uses:
Amateur Astronomy:
Dobsonians are often favored by amateur astronomers for their ease of use and affordability. They provide impressive views of a wide range of celestial objects.
Deep-Sky Exploration:
With larger apertures, Dobsonian telescopes are excellent for observing faint deep-sky objects beyond our solar system.
Component of Telescope
Objective Lens :
The objective lens is a large, convex lens used at the front of the telescope. It gathers and refracts the light to bring it to a focus point.
Primary Mirror :
The primary mirror is a curved, usually parabolic mirror. This is located at the bottom of the telescope tube. It reflects and gathers light, directing it to the secondary mirror.
Secondary Mirror :
Secondary mirror is located in front of the primary mirror. It reflects the focused light to the eyepiece.
Eyepiece :
The eyepiece is the location from which an observer is able to view the magnified image. It further magnifies the focused light produced by the objective lens or primary mirror. Different eyepieces provide varying levels of magnification, allowing observers to adjust the telescope’s view based on their preferences and the nature of the celestial object being observed.
Focuser :
The focuser allows the observer to adjust the position of the eyepiece, and helps to tune the focus of the telescope. Some telescopes have manual focusers, while others may have electronic focus controls.
Mount :
The mount is used to provide support for the telescope, it provides stability and allows for adjustments in both altitude (up and down) and azimuth (left and right). There are two types of mounts: alt-azimuth (up-down, left-right) and equatorial (aligned with Earth’s rotation).
Tube or Optical Tube Assembly (OTA) :
The tube holds the components of the telescope. It protects the mirrors or lenses from dust, moisture, and other environmental factors.
Finderscope :
The finderscope is a small, low-powered telescope or sight which is attached to the main telescope. It helps to locate celestial objects by providing a wider field of view, making it easier to center objects before observing through the main telescope.
Aperture :
The diameter of the objective lens or primary mirror is known as aperture. It determines the amount of light that a telescope can gather. Larger apertures allow for better resolution and visibility of faint objects.
Mounting Accessories :
Telescopes may include additional accessories such as counterweights (to balance the telescope), slow-motion controls (for precise adjustments), and GoTo systems (computerized mounts that can automatically locate and track celestial objects).
Tripod (for Portable Telescopes) :
Portable telescopes often come with tripods to provide a stable base. Tripods are essential for terrestrial observations or when stargazing away from a fixed observatory.
