Real-World Testing: Putting Celestron CPC 800 GPS XLT Computerized 8″ Schmidt-Cassegrain Telescope to the Test
First Use Experience
My first test of the Celestron CPC 800 GPS XLT took place at a remote dark sky site about an hour outside of the city. The site is known for its minimal light pollution. I wanted to experience the telescope’s full potential under optimal conditions.
The conditions were nearly perfect, with clear skies and minimal humidity, though temperatures dipped to around 40°F. The GPS alignment was surprisingly quick and accurate, taking only a few minutes to pinpoint the telescope’s location and orient itself. Locating and tracking celestial objects was then simple, thanks to the intuitive hand controller.
The only initial issue I encountered was related to the weight and bulk when setting up in the cold. While portable, managing the 42 lbs in the dark required a bit of planning. I learned quickly to organize my setup to minimize trips back and forth to the car.
Extended Use & Reliability
After several weeks of consistent use, the Celestron CPC 800 GPS XLT has proven to be a reliable and rewarding instrument. The optical quality continues to impress, delivering sharp and detailed views of planets, nebulae, and galaxies. The StarBright XLT coatings make a noticeable difference in image brightness and contrast.
Durability has also been commendable. Despite being transported and set up in various locations, the telescope has shown no signs of wear and tear. The sturdy tripod provides a stable platform, even in slightly windy conditions.
Maintenance is straightforward. The optical tube requires occasional cleaning with appropriate lens cleaning solutions, and the mechanical components benefit from infrequent lubrication. Compared to my previous telescopes, which often required more frequent collimation adjustments, the Celestron CPC 800 GPS XLT has maintained its optical alignment remarkably well.
Breaking Down the Features of Celestron CPC 800 GPS XLT Computerized 8″ Schmidt-Cassegrain Telescope
Specifications
The Celestron CPC 800 GPS XLT Computerized 8″ Schmidt-Cassegrain Telescope boasts an 8-inch (203.2 mm) aperture, providing excellent light-gathering ability. The focal length is 2032 mm, resulting in a focal ratio of f/10, ideal for high-magnification observations of planets and deep-sky objects. The StarBright XLT optical coatings enhance light transmission, improving image brightness and contrast.
The telescope has a magnification range of 29x to 480x, offering versatility for observing a wide range of celestial objects. Its limiting magnitude of nearly 15 means it can reveal faint objects invisible to the naked eye or smaller telescopes. The integrated GPS receiver automatically determines the telescope’s location and time, simplifying the alignment process.
These specifications are significant because they directly impact the viewing experience. The large aperture gathers more light, allowing for brighter and more detailed views of faint objects. The StarBright XLT coatings further enhance image quality by minimizing light loss due to reflection. The GPS functionality streamlines setup, making it easier to start observing quickly and accurately.
Performance & Functionality
The Celestron CPC 800 GPS XLT performs exceptionally well, delivering clear and detailed views of a variety of celestial objects. The computerized GoTo system accurately points the telescope to desired targets, making it easy to explore the night sky. The tracking system keeps objects centered in the field of view, compensating for Earth’s rotation.
The telescope excels at planetary observations, revealing details on the surfaces of Jupiter, Saturn, and Mars. It also performs admirably on deep-sky objects, such as nebulae and galaxies, bringing faint objects into view with surprising clarity.
The main strength is definitely the GoTo accuracy. Its weakness lies in its vulnerability to dew formation on the Schmidt corrector plate during humid nights, requiring a dew shield or heater. Overall, it exceeds expectations, delivering on its promise of a portable yet powerful observing experience.
Design & Ergonomics
The Celestron CPC 800 GPS XLT features a well-thought-out design. While the 42lb weight requires consideration, the conveniently placed carrying handles make transport manageable. The sturdy tripod provides a stable platform, minimizing vibrations and ensuring clear images.
The hand controller is intuitive and easy to use, even in the dark. The telescope has an ergonomic design. This makes it comfortable to operate for extended observing sessions.
The telescope is generally user-friendly, although the initial setup and alignment process may require some familiarization. However, after a few sessions, the process becomes second nature.
Durability & Maintenance
The Celestron CPC 800 GPS XLT is built to last, with high-quality materials and robust construction. The optical tube is made of durable aluminum, and the tripod is made of sturdy steel. The electronics are well-protected, and the telescope is designed to withstand moderate outdoor conditions.
With proper care and maintenance, the Celestron CPC 800 GPS XLT should provide years of reliable service. The optical surfaces should be cleaned regularly with appropriate lens cleaning solutions. The mechanical components should be lubricated periodically.
