7 min read

Observing the solar system with a telescope can be an exciting and rewarding experience for astronomy enthusiasts. By using a telescope, you can get a closer look at the planets, moons, and other celestial objects in our solar system. In this article, we will guide you on how to observe the solar system with a telescope, from choosing the right equipment to exploring the wonders of our cosmic neighborhood.

Choosing the Right Telescope

Choosing The Right Telescope

Before you can start observing the solar system, you need to choose the right telescope for your needs. There are various types of telescopes available, such as refractor, reflector, and compound telescopes. Each type has its own advantages and disadvantages, so it’s important to do some research and consider factors like portability, budget, and desired magnification.

A refractor telescope uses lenses to gather and focus light. It is a popular choice for beginners due to its simplicity and low maintenance. Refractors provide clear and crisp images, making them ideal for observing the Moon and planets. However, they tend to be more expensive for larger apertures.

A reflector telescope uses mirrors to gather and focus light. It offers larger apertures at an affordable price, making it suitable for observing deep-sky objects like galaxies and nebulae. Reflectors require occasional collimation, which is the alignment of the mirrors, to maintain optimal performance.

A compound telescope, also known as a catadioptric telescope, combines lenses and mirrors to provide a compact and versatile design. This type of telescope offers a good balance between portability and performance, making it suitable for both planetary and deep-sky observations. However, compound telescopes can be more expensive compared to refractors and reflectors.

Considerations for Choosing a Telescope

When choosing a telescope, consider the following factors:


The aperture refers to the diameter of the objective lens or primary mirror. It determines the amount of light the telescope can gather. A larger aperture allows for better resolution and the ability to see fainter objects. However, larger apertures also mean bulkier and more expensive telescopes. Consider your observing goals and budget when deciding on the aperture size.


The magnification of a telescope is determined by the combination of the focal length of the telescope and the eyepiece used. Higher magnification allows for closer views of objects, but it also reduces the field of view and image brightness. Keep in mind that atmospheric conditions and telescope stability can limit the practical magnification. It’s recommended to start with lower magnifications for initial observations.

Mount and Stability:

The mount is an essential component of a telescope as it provides stability and allows for smooth tracking of celestial objects. There are two main types of mounts: alt-azimuth (AZ) and equatorial (EQ). An alt-azimuth mount is simpler to use and doesn’t require polar alignment, but it can be limiting for long-exposure astrophotography. An equatorial mount requires polar alignment but provides tracking capabilities for astrophotography and more convenient manual tracking.


Set a budget for your telescope purchase. It’s important to find a balance between your desired features and affordability. Consider not only the telescope itself but also additional accessories like eyepieces, filters, and a sturdy tripod or mount.

Research different telescope models, read reviews, and visit local astronomy clubs or stores to get hands-on experience with telescopes. Take your time to make an informed decision based on your needs and preferences.

Setting Up Your Telescope

Setting Up Your Telescope

Once you have selected a telescope, it’s time to set it up for observation. Find a suitable location with minimal light pollution, as it can interfere with your viewing experience. Light pollution filters are also available to minimize the impact of artificial lights.

Dark Sky Sites:

Consider visiting dark sky sites, which are areas with minimal light pollution. These sites provide optimal conditions for observing faint objects in the sky. Check local regulations and safety guidelines before planning a trip to a dark sky site.

Assembling the Telescope:

Follow the manufacturer’s instructions for assembling the telescope. Start by attaching the optical tube to the mount or tripod. Ensure that all screws and connections are tightened properly to avoid any instability during observation.

Mount Alignment:

For telescopes with an equatorial mount, it’s important to align the mount with the celestial pole. This process, known as polar alignment, ensures accurate tracking of objects as they move across the sky. There are various methods and tools available for polar alignment, including polar alignment scopes and smartphone apps.

Calibrating the Finder Scope:

Finder scopes are small telescopes mounted on the main telescope used for locating objects. It’s crucial to calibrate the finder scope to ensure that it accurately points to the desired objects. Align the finder scope with the main telescope by selecting a distant terrestrial object and adjusting the alignment screws until the object is centered in both scopes.

Observing the Planets

Observing The Planets

The planets in our solar system offer a fascinating sight when observed through a telescope. Each planet has its own unique features that can be observed with varying levels of details.

Starting with Venus:

Venus is the brightest planet in our solar system and often referred to as the “Evening Star” or “Morning Star.” It can be easily spotted in the evening or morning sky. When observing Venus, you can notice its phases, similar to the phases of the Moon. Use a moderately high magnification to observe the planet’s cloud patterns and any visible atmospheric features.

Exploring Mars:

Mars, often called the “Red Planet,” is known for its reddish appearance in the night sky. Observe Mars during its opposition, when it is closest to Earth. This is the best time to see surface features such as dark regions, polar ice caps, and even dust storms. Higher magnifications can reveal more details on the Martian surface.

Discovering Jupiter:

Jupiter is the largest planet in our solar system and exhibits a fascinating array of features. Its most prominent feature is the Great Red Spot, a giant storm system larger than Earth. Look for cloud bands, atmospheric belts, and the four largest moons of Jupiter, known as the Galilean moons. Higher magnifications can reveal intricate details in Jupiter’s cloud patterns.

Observing Saturn’s Rings:

Saturn is famous for its stunning ring system, which makes it one of the most visually appealing planets to observe. When observing Saturn, use a moderate to high magnification to see the ring system and its divisions. You can also observe Saturn’s largest moon, Titan, and other smaller moons that orbit the planet.

Examining Other Planets:

Other planets, such as Mercury and Uranus, can also be observed with a telescope. However, due to their small sizes and/or distance, they may appear as tiny dots without much surface detail. Nevertheless, observing these planets can still provide a sense of their presence in the solar system.

Exploring the Moon

Exploring The Moon

The Moon is another celestial object that is worth observing with a telescope. Its craters, mountains, and valleys provide a glimpse into the lunar landscape.

Identifying Lunar Features:

Start by identifying prominent features on the Moon’s surface, such as the Sea of Tranquility (Mare Tranquillitatis), which was the landing site for the Apollo 11 mission. Look for craters, mountain ranges, and lunar mare (dark, smooth areas). Observe the differences in brightness and texture across the lunar surface.

Phases of the Moon:

As the Moon orbits Earth, it goes through different phases, ranging from a thin crescent to a full moon and back. Observing the various phases of the Moon can be an intriguing experience. Pay attention to the terminator line, which is the boundary between the illuminated and dark portions of the Moon. This line enhances the visibility of lunar features, especially when it’s near the first quarter or last quarter phase.

Experimenting with Filters:

Filters can enhance lunar observations by reducing glare and improving contrast. A neutral density (ND) filter can help reduce the brightness of the Moon, allowing for better visibility of details. A color filter, such as a blue or orange filter, can enhance the contrast of specific lunar features or bringout certain colors on the lunar surface. Experiment with different filters to find the ones that work best for your observations.

Capturing Lunar Images:

If you’re interested in astrophotography, the Moon is a great subject to start with. Use a smartphone adapter or a dedicated lunar imaging camera to capture detailed images of the Moon’s surface.
