The specifications of the Sky-Watcher 200P telescope are impressive, making it a valuable investment for stargazing enthusiasts.
To further illustrate their significance, let’s examine each specification in detail to see how they can enhance your overall stargazing experience.
Aperture
The aperture of the Sky-Watcher 200P is 200mm, which is considered large for a telescope in this price range. A larger aperture allows for better light-gathering capability, which means more light is collected and focused. This results in clearer, more detailed visual observing of celestial objects.
With the Sky-Watcher 200P’s large aperture, you can observe galaxies, nebulae, and star clusters in great detail.

Focal length
The focal length of the Sky-Watcher 200P is 1200mm, which is a good balance between magnification and field of view. With a longer focal length, you’ll be able to achieve higher magnification, which is ideal for observing planets and other small celestial objects.
However, a longer focal length also means a narrower field of view. The 1000mm focal length of the Sky-Watcher 200P strikes a good balance between magnification and field of view, making it versatile for a wide range of observations.
Focal ratio
The Sky-Watcher 200P has a focal ratio of f/5.9, which means it has a relatively fast focal ratio. This makes the telescope better suited for observing bright objects such as planets, star clusters, and nebulae.
With this focal ratio, you’ll be able to achieve a bright, detailed view of these celestial objects.
Magnification
The Sky-Watcher 200P telescope has a magnification range of 40x to 400x, which is quite impressive. However, it’s important to keep in mind that magnification isn’t everything when it comes to observing celestial objects.
A high magnification doesn’t necessarily mean a clearer or more detailed view. Factors such as aperture, focal length, and atmospheric conditions all play a role in the clarity and detail of your observations.

Optical design
The Sky-Watcher 200P uses a parabolic Newtonian reflector optical design, ideal for observing deep-sky objects such as galaxies, nebulae, and star clusters.
This design offers excellent light-gathering capability and produces clear, sharp images.
However, it’s important to keep in mind that reflector telescopes require occasional collimation (alignment of the mirrors) to maintain optimal performance.
Mount type
The Sky-Watcher 200P’s alt-azimuth mount has two axes of motion: altitude and azimuth. The altitude axis allows you to move the telescope up and down, while the azimuth axis allows you to move it left and right.
The mount has manual slow-motion controls that allow you to make fine adjustments to the telescope’s position.
Though computerized telescopes are great, finding objects manually with a star chart can also be fulfilling.
Maximum practical magnification
The maximum practical magnification of the Sky-Watcher 200P is 400x, which is also quite impressive. However, as mentioned earlier, magnification isn’t everything when it comes to observing celestial objects.
Factors such as aperture, atmospheric conditions, and the quality of the optics are important.
Limiting stellar magnitude
The limiting stellar magnitude of the Sky-Watcher 200P telescope is 14, which is a measure of the faintest star that can be seen with the naked eye under ideal observing conditions.
The limiting stellar magnitude is an important specification for astronomers as it indicates the telescope’s ability to observe faint objects.
With a limiting stellar magnitude of 14, the Sky-Watcher 200P telescope can observe a wide range of celestial objects, including galaxies, nebulae, and star clusters.
Eyepiece diameter
The Sky-Watcher 200P telescope has a 1.25-inch eyepiece diameter, which is a common size for telescopes in its class. The eyepiece diameter determines the field of view and magnification of the telescope.
With a 1.25-inch eyepiece diameter, the telescope can provide a wide field of view and a range of magnification options. The telescope comes with two eyepieces (10mm and 25mm) that provide magnifications of 40x and 100x, respectively.
Optical tube
The optical tube of the Sky-Watcher 200P telescope is a cylindrical tube made of rolled steel with a black high-gloss finish. It has a diameter of approximately 235mm and a length of about 920mm, making it a fairly large and substantial component of the telescope.
The tube houses the 200mm primary mirror and 47mm secondary mirror, which work together to collect and focus light onto the eyepiece.
The optical tube also includes a 2-inch Crayford focuser with a 1.25-inch adaptor, which allows for precise focusing of the telescope.
The optical tube is a critical part of the Sky-Watcher 200P telescope, as it is responsible for gathering and focusing the light that enables users to view celestial objects in detail.
Patented tension control handle
The Sky-Watcher 200P telescope comes with a patented tension control handle, which is a feature of the Dobsonian mount that the telescope sits on.
The tension control handle is designed to allow for smooth and easy movement of the telescope while also providing a level of resistance to keep the telescope steady and prevent it from drifting when focusing on a celestial object.
This feature allows for precise adjustments to be made while viewing objects in the night sky, making it easier to track moving objects and achieve sharper focus.
Sky-Watcher 200P accessories
The Sky-Watcher 200P Telescope comes with a set of accessories that are designed to enhance your stargazing experience.
Let’s examine some accessories and discuss how they can help you get the most out of your telescope.
10mm and 25mm Plossl eyepieces
The 10mm and 25mm Plossl eyepieces are standard 1.25-inch eyepieces that provide medium and high magnification views of the night sky.
The Plossl design provides good eye relief and clear views of objects, making it easy to observe objects with fine details.
The 10mm eyepiece provides a higher magnification view, making it ideal for observing objects with more detail, while the 25mm eyepiece provides a wider field of view, making it ideal for locating objects.
This classic 200p Dobsonian also has a 2-inch eyepiece adapter.
9×50 finderscope
The 9×50 finderscope is a small telescope mounted on top of the main telescope tube that helps you locate objects. It provides a wider field of view than the main telescope, making it easier to locate objects.
The 9x magnification also makes it easier to see faint objects that may be difficult to see with the naked eye.
The finder scope is equipped with crosshairs that help you center objects in the eyepiece for easier observation.
Sky-Watcher 200P optical performance
The Sky-Watcher 200P telescope is known for its excellent optical performance, which is due to its large aperture and focal length. The telescope has a 200mm aperture and a 1200mm focal length, which makes it ideal for observing deep sky objects.
The telescope also has a fast focal ratio of f/5.9, which means it can gather a lot of light quickly, making it ideal for observing faint objects.
What is the price of Sky-Watcher 200P?
On average, the Sky-Watcher 200P telescope costs between $500-$700, making it a mid-range telescope affordable for most stargazers. However, the price varies depending on the retailer and any additional accessories that may be included in the package.
