What Makes Celestron CGEM II 1100 EdgeHD Telescope, 11in, Stand Out?
The Celestron CGEM II 1100 EdgeHD Telescope, 11in, is not just another telescope; it’s a gateway to the cosmos. Manufactured by Celestron, this telescope combines a large 11-inch aperture with their signature EdgeHD optics, promising breathtaking views of deep-sky objects and planetary details. With a hefty price tag of $5699.00, it sits firmly in the advanced amateur to semi-professional category.
As an experienced outdoor and tactical gear specialist, my journey into astronomy might seem a bit of a departure. But a clear night under a star-filled sky during a backcountry trek sparked a renewed sense of wonder, leading me to seek a tool that could bring those celestial wonders closer.
The Celestron CGEM II 1100 EdgeHD Telescope, 11in, arrived in several large, well-protected boxes. Assembling it was a multi-stage process, immediately highlighting the instrument’s robust build quality. The materials felt premium, and the mount seemed incredibly solid, promising stable tracking.
I considered the Meade LX200 ACF 12″ and the Sky-Watcher Esprit 150ED APO refractor before settling on the Celestron CGEM II 1100 EdgeHD Telescope, 11in,. While the Meade offered a slightly larger aperture, the Celestron’s EdgeHD optics promised superior edge-to-edge sharpness. The Sky-Watcher offered incredible wide-field views, but lacked the light-gathering ability for deep-sky observation that the Celestron offered.
My first impression was a mix of excitement and intimidation. Its size and complexity were a little daunting, but the promise of stunning celestial views overshadowed any apprehension.
Real-World Testing: Putting Celestron CGEM II 1100 EdgeHD Telescope, 11in, to the Test
First Use Experience
I tested the Celestron CGEM II 1100 EdgeHD Telescope, 11in, at a dark-sky location about two hours outside the city. This location offered minimal light pollution, which is crucial for observing faint deep-sky objects. The first night was clear and cold, with temperatures hovering around freezing.
The CGEM II mount, though robust, required a precise polar alignment, which took some time to master. Once aligned, the GoTo system accurately located numerous objects, including the Orion Nebula, the Andromeda Galaxy, and several globular clusters. Even in the cold, the electronics performed flawlessly.
The initial views through the EdgeHD optics were nothing short of spectacular. The sharpness and clarity, especially across the entire field of view, were immediately noticeable. I did experience some dew formation on the corrector plate due to the cold, requiring the use of a dew shield and eventually a dew heater.
Extended Use & Reliability
After several months of use, the Celestron CGEM II 1100 EdgeHD Telescope, 11in, has proven to be a reliable and capable instrument. The CGEM II mount consistently tracks accurately, essential for long-exposure astrophotography. While the initial learning curve was steep, the GoTo system has become second nature.
The telescope shows no significant signs of wear and tear, despite being transported to several different observing locations. The optical tube assembly is particularly well-constructed. Cleaning the optics requires care and specialized solutions, but it’s a manageable task.
Compared to my previous 8-inch Schmidt-Cassegrain telescope, the Celestron CGEM II 1100 EdgeHD Telescope, 11in, offers a significant improvement in both light-gathering ability and image quality. The EdgeHD optics are truly exceptional, delivering sharp, high-contrast images that reveal details I had never seen before.
Breaking Down the Features of Celestron CGEM II 1100 EdgeHD Telescope, 11in,
Specifications
- Aperture: 11 inches (280 mm). This large aperture allows for collecting a significant amount of light, enabling observation of faint deep-sky objects.
