Best Blog Review – To observe celestial bodies at night, a telescope is needed to get a clearer image. However, the level of clarity of images produced by space telescopes is influenced by several things. Aperture and magnification settings are aspects that affect the results of observations become clearer or not.
If you want to observe objects in the sky at night, you can provide your own space telescope. With a telescope, you can observe the constellations of stars, the planet Venus, the star Antares, and other celestial bodies. To get the best picture of your observations, make sure you use a quality space telescope.
Although it looks simple, the telescope has other components that have a more important role. While the main part of any telescope is generally the main body in the form of an elongated telescope tube, a gantry which is a link between the telescope and a tripod that can be moved in all directions, and a tripod that supports the telescope and gantry.
Usually, when buying a space telescope, the manufacturer has prepared a complete set of these main components. In addition, the telescope can also be adjusted using a computer by entering determinant variables, such as constellation and gantry settings. When buying a telescope, you will come across several types. Let’s understand each type of space telescope below.
1. Choose a telescope by type and pay attention to its characteristics
If distinguished, space telescopes are divided into two types, namely refractor telescopes and reflecting telescopes. These two types of telescopes are the most commonly used. However, there is also another type of telescope that combines the functions of a refractor telescope and a reflecting telescope, namely a catadioptric telescope. What are the characteristics of each of these types of telescopes?
# Refractory Telescope .
This telescope is most widely used by astronomers, ranging from beginner and professional levels. The ease of operation makes this telescope suitable for those of you who are first time observing celestial bodies from a telescope.
With this telescope, you can aim the telescope at various angles. A relatively stable field of view when viewing also reduces you to make changes.
# Reflector Telescope
Reflector telescopes allow you to observe celestial bodies that are smaller than planets or stars, such as nebulae, galaxies, and comets. His ability to capture the shadows of celestial bodies with small light intensity makes the object picture clearer.
Reflector telescopes have one or more concave mirrors to detect celestial bodies by reflecting light and their images. Unlike the refractor type, reflector telescopes place the finderscope on the side of the body. It’s better to learn the operation of the finderscope first so that you get used to it and can use it smoothly.
# Catadioptric Telescope
Catadioptric telescope is a combination of refractor type and reflector or reflection. This tool has a concave lens and mirror to emphasize the image of celestial bodies. Generally, this model telescope has the function of correcting the color and curvature of the object’s shadow during observation.
Some examples of catadioptric telescopes include Schmidt-Cassegrain and Maksutov. This telescope is quite easy to use. Its compact size is also flexible to move. For the ability to capture the reflection of light and shadows of celestial bodies from this type of telescope, it depends on the manufacturer. Choose a product from a trusted manufacturer so you won’t be disappointed by the poor quality of the telescope.
2. 3Check the lens diameter size
In every space telescope there are two lenses or mirrors, namely the objective lens and the eyepiece. The position of the lens in front is called the objective lens, its function is to focus the image. While the eyepiece or eyepiece is located at the back and acts as a magnifying image.
The ability to capture light is influenced by the size of the objective lens diameter is called aperture. The larger the diameter of the objective lens, the greater its ability to capture light. As a result, the shadows of celestial objects appear clearer and sharper. If you want to block out more light at night, choose a space telescope that has a large aperture.
3. Also check the ability of the lens to zoom
Objects in the form of objects in outer space are so far away that their size seems so small that it is difficult for our naked eyes to reach. Tools such as telescopes were created to help get clearer images of objects. This level of clarity is influenced by the objective lens and the eyepiece.
The magnification of the telescope lens can be adjusted so that better observations are produced. Between the magnification and the diameter of this lens must be correlated with each other so as to obtain the maximum magnification for sharper and clearer shots.
The effective magnification of each telescope is 1.5 – 2 times the diameter of the objective lens. For example, if the objective lens has an aperture of 60 mm, the effective magnification is 60 – 120 times. When the objective lens has an aperture of 200 mm, the effective magnification is 300 – 400 times.
Now you know about the types of telescopes and their respective characteristics. Are you ready to observe the heavenly bodies? Here, Ainun introduces the 10 best space telescopes from trusted brands. Happy choosing!
While the two eye lenses measuring 6 mm and 20 mm, have a magnification of 60 and 18 times, respectively. Manufacturers equip telescopes with tripods made of aluminum. The tripod is sturdy enough to accommodate the telescope tube, while the gantry can be rotated and adjusted easily.
Visionking provides two eyepieces that can be replaced according to the magnification you want to provide, namely 12 and 19 times. The building materials of aluminum and plastic not only make this device practical for children who are just learning, but it is also lightweight and durable.
The objective lens has a diameter of 50 mm which is equipped with an ISO standard solar filter. The finderscope on this telescope is equipped with a solar safe so that it can protect your eyes when observing the sun. This tool can also be used to observe the occurrence of a solar eclipse clearly.
This telescope became the mainstay of middle-level astronomy safeguards. The eyepiece in this tool consists of three pieces with different magnification levels, ranging from low magnification (6.3 mm), medium (9 mm), and high (26 mm).
Observe space objects with sharper and clearer images with this reflector-type telescope. With a minimum magnification of 11x and a maximum magnification of 118x, this telescope is even more ideal for viewing your favorite space objects!
The Sky Tour handset with an LCD that can tell you about the constellations, amazing facts about space, and myths about outer space will keep you from getting bored every time you use it. The supplied 8 mm and 12.5 mm diameter eyepieces have extremely high accuracy and magnification.
If you want to find the location of a space object, use an eyepiece with a diameter of 25 mm. If you want to make a nearby observation at a designated location, switch to a 6 mm eyepiece for further observation. The focal length of the lens reaches 360 mm allowing it to produce clearer images of space.
Designed from good quality aluminum, this telescope can last you for years. Carrying this telescope is also not a problem because it is relatively light in weight. However, the tripod provided is too low, so for those of you who are tall, it will feel uncomfortable.
Observations given by this telescope can be made clear through an objective lens with a diameter of 60 mm with magnifications ranging from 25 – 75 times. If you want to observe a celestial object that is farther away, you will need to add a lens with a large aperture so that the capture is clearer.
This refractor type telescope with an objective lens diameter of 50 mm and an eyepiece that can be magnified between 30 – 60 times will help you observe space objects from near to far. The main components are easy to disassemble making it very portable, you don’t even need a screwdriver to attach the bolts to this tool.
You can now look at celestial objects using a space telescope. Make sure your chosen product is able to present space objects clearly enough. For this reason, it is important to check the maximum magnification of your telescope’s objective lens. With effective magnification, you can more clearly see the shadow of objects in the sky.
