The universe is a vast and mysterious place, and stargazing is one of the most exciting ways to explore it. Sky Watcher GTI 150P is a telescope that offers an excellent viewing experience for both beginners and experienced astronomers. With a 150mm aperture, this telescope is perfect for observing deep-sky objects such as galaxies, nebulae, and star clusters.
The Sky-Watcher Heritage 150P is a larger version of the beloved Heritage 130P (also known as the Astronomers Without Borders OneSky), which has been available for some time. The 150P is a recent introduction to the telescope market, particularly in the US, which attempts to scale up the 130P design to add another inch of aperture. It uses the same optics as popular 6” f/5 scopes, some of which are tabletop Dobsonians, but with the Heritage 130P’s collapsible tube and plastic upper tube assembly.
Before the COVID-19 pandemic and associated changes in the retail world, the Heritage 150P wasn’t exactly a screaming deal – it was priced similarly to popular 6” f/8 Dobsonians, and unlike them, it needs a table after all (and some other things we’ll get to later) – but due to inflation and supply chain issues, the Heritage 150P is now significantly cheaper than any other 6” Dobsonians available. A completely certain explanation for why is unknown, but it could be that the Heritage 150P is an order of magnitude less bulky dimensionally in its shipping box than a full-sized Dobsonian and even smaller than some other tabletop 5” and 6” scopes, which would explain why it has not changed in price and its sibling the 130P has had only a modest markup.
When purchasing a telescope, there are a few critical factors to consider, such as aperture size, focal length, and mount type. The aperture size determines the amount of light the telescope can gather, which affects the quality of the image. The focal length determines the magnification power of the telescope, while the mount type determines the stability and ease of use. The Sky Watcher GTI 150P has a sturdy EQ5 mount that provides smooth and precise movements, making it easy to track objects in the sky.
We spent hours researching and testing various telescopes to identify the ones that offer the best viewing experience. The Sky Watcher GTI 150P stood out for its exceptional performance and ease of use. Whether you’re a beginner or an experienced astronomer, this telescope is an excellent choice for exploring the universe.

Buying Guide
When looking to purchase a Sky Watcher GTI 150P, there are a few important factors to consider. We recommend taking the following into account to ensure that you choose the best product for your needs.
Aperture Size
The aperture size is one of the most important factors to consider when purchasing a Sky Watcher GTI 150P. This refers to the diameter of the telescope’s primary lens or mirror. The larger the aperture, the more light the telescope can gather, resulting in brighter and clearer images. We recommend choosing a telescope with an aperture size of at least 6 inches (150mm) for optimal viewing.
Focal Length
The focal length is another important factor to consider when purchasing a Sky Watcher GTI 150P. This refers to the distance between the primary lens or mirror and the point where the image is focused. A longer focal length will result in a narrower field of view, while a shorter focal length will result in a wider field of view. We recommend choosing a focal length that suits your needs, depending on the type of objects you plan to observe.
Mount Type
The mount type is also an important consideration when purchasing a Sky Watcher GTI 150P. There are two main types of mounts: equatorial and altazimuth. Equatorial mounts are better suited for astrophotography and tracking celestial objects, while altazimuth mounts are easier to use and better suited for visual observing. We recommend choosing a mount type that best suits your needs and level of experience.
Additional Features
There are a number of additional features that may be worth considering when purchasing a Sky Watcher GTI 150P. These may include:
- GoTo functionality: This feature allows the telescope to locate and track celestial objects automatically.
- Eyepieces: Different eyepieces can provide different magnifications and fields of view.
- Barlow lens: This accessory can increase the magnification of your telescope.
- Collimation tools: These tools can help you align the mirrors or lenses in your telescope for optimal performance.
Overall, when purchasing a Sky Watcher GTI 150P, it’s important to consider your needs and level of experience, as well as the telescope’s aperture size, focal length, mount type, and additional features.
