Cassini C-80EFS 800 mm x 80 mm Reflector Telescope Review

Let’s Talk About Cassini C-80EFS 800 mm x 80 mm Reflector Telescope

The Cassini C-80EFS 800 mm x 80 mm Reflector Telescope offers an accessible entry point into the fascinating world of astronomy. Manufactured by Cassini, this reflector telescope boasts an 80mm aperture and an 800mm focal length, promising decent views of the Moon, planets, and some brighter deep-sky objects. The inclusion of a wireless electronic focuser and the Mars’ Eye electronic finderscope are features that piqued my interest, as they suggest a blend of traditional optics with modern convenience.

My interest in the Cassini C-80EFS stemmed from a desire to introduce my children to astronomy. I wanted a telescope that wouldn’t break the bank but still provided a worthwhile observing experience. I was looking for a telescope that was relatively easy to set up and use, so we could spend more time observing and less time struggling with complicated equipment.

Unboxing the Cassini C-80EFS, I was immediately struck by the overall lightweight feel of the components. The metal tripod seemed sturdy enough, but the optical tube assembly felt a bit more lightweight than I expected. The finish on the white optical tube was clean and the overall design was visually appealing, creating a sense of anticipation for the night sky.

I considered the Celestron AstroMaster 70AZ and the Orion SpaceProbe 76mm Reflector Telescope, both within a similar price range. I chose the Cassini C-80EFS for its advertised features, including the electronic focuser and the Mars’ Eye finderscope, which I hoped would simplify the focusing and aiming processes for my kids. These features appeared to offer more assistance for beginners compared to the simpler designs of the other models.

My first impression was cautiously optimistic. The telescope seemed well-packaged and had some promising features, but I was concerned about the build quality and the potential for shaky images due to the lightweight components. Only a night under the stars would reveal the true potential of the Cassini C-80EFS 800 mm x 80 mm Reflector Telescope.

Real-World Testing: Putting Cassini C-80EFS 800 mm x 80 mm Reflector Telescope to the Test

First Use Experience

I tested the Cassini C-80EFS in my backyard, which offers relatively dark skies compared to the center of town. We aimed for the Moon first, as it’s an easy target to locate and provides immediate visual feedback on the telescope’s performance.

The telescope performed adequately in the calm, cool evening. The images of the Moon, while not breathtaking, were clear enough to discern craters and lunar features. The electronic focuser, while a nice idea, was a little sluggish and didn’t provide the fine-tuning I was hoping for.

The initial setup was straightforward, but aligning the Mars’ Eye finderscope proved to be a bit tricky. The electronic finderscope projected a red dot onto the sky, however the dot was a little dim and hard to see. I also had to adjust to using the altitude azimuth mount, which requires some coordination to track celestial objects.

Extended Use & Reliability

After several weeks of use, the Cassini C-80EFS has held up reasonably well, though some minor issues have surfaced. The tripod, while initially stable, has become a bit wobbly over time, especially on uneven surfaces.

There are no major signs of wear and tear, but the plastic components on the focuser and finderscope feel a bit fragile. Cleaning the optics has been relatively simple, requiring only a soft cloth and some lens cleaning solution.

Compared to my older 60mm refractor telescope, the Cassini C-80EFS offers slightly brighter and sharper images, but the difference isn’t as dramatic as I had anticipated. The greater aperture provides more light-gathering capability, but the overall image quality is still limited by the telescope’s design and included eyepieces.

Breaking Down the Features of Cassini C-80EFS 800 mm x 80 mm Reflector Telescope

Specifications

The Cassini C-80EFS 800 mm x 80 mm Reflector Telescope boasts an 80mm objective aperture, which is the diameter of the primary mirror that gathers light. A larger aperture generally means brighter and more detailed images.

The telescope has an 800mm focal length, the distance between the primary mirror and the point where light converges to form an image. This, coupled with the aperture, yields a focal ratio of f/10, indicating a relatively “slow” telescope that is better suited for high-magnification views of brighter objects like the Moon and planets.

The Cassini C-80EFS includes two eyepieces: a 20mm and a 6mm. These eyepieces provide magnifications of 40x and 133x, respectively. An altitude azimuth yoke mount allows for up-and-down and left-and-right movement.

The Optical Coating is Aluminized w/Silicon Monoxide Quartz Overcoat. The Finderscope is a Red-dot.

These specifications determine the telescope’s light-gathering ability, magnification range, and ease of use. The 80mm aperture provides decent light-gathering capability for viewing the Moon and planets, while the included eyepieces offer a range of magnifications for different observing scenarios. The Electronic Wireless Focuser is intended to improve image viewing.

Performance & Functionality

The Cassini C-80EFS 800 mm x 80 mm Reflector Telescope performs adequately for its price range, providing acceptable views of the Moon, planets, and some brighter deep-sky objects. The included eyepieces are functional, but upgrading to higher-quality eyepieces would significantly improve image sharpness and contrast.

The electronic focuser is a mixed bag. It allows for hands-free focusing, but it can be slow and imprecise. The Mars’ Eye finderscope is helpful for aiming the telescope, but it can be difficult to see the red dot in brighter environments.

The altitude azimuth mount is relatively easy to use, but it can be challenging to track objects at high magnifications. The slow-motion altitude adjustment rod helps with fine-tuning the telescope’s vertical position, but the overall stability of the mount could be better.

Design & Ergonomics

The Cassini C-80EFS has a simple and functional design. The metal tripod provides a reasonably stable base, but it can be wobbly on uneven surfaces. The optical tube assembly is lightweight, making it easy to move and transport.

The telescope is relatively user-friendly, but aligning the finderscope and mastering the altitude azimuth mount require some practice. The electronic focuser is a convenient feature, but it can be a bit finicky to use.

The assembly process is fairly straight forward, but not intuitive. The instruction manual could use better illustrations and clearer step-by-step directions.

Durability & Maintenance

The Cassini C-80EFS 800 mm x 80 mm Reflector Telescope seems reasonably durable for its price range. The metal tripod and optical tube assembly should withstand normal use, but the plastic components on the focuser and finderscope may be more susceptible to damage.

Maintaining the telescope is relatively simple. Cleaning the optics requires only a soft cloth and some lens cleaning solution. Storing the telescope in a dry environment will help prevent corrosion and other damage.

The aluminized mirror with the Silicon Monoxide Quartz overcoat should last several years with careful handling. Avoid touching the surface of the mirrors.

Accessories and Customization Options

The Cassini C-80EFS comes with two eyepieces (20mm and 6mm), a Mars’ Eye electronic finderscope, a wireless electronic focuser, and a planetarium CD-ROM. The included 3x Astroscopic Barlow lens will increase magnification, but can reduce the overall image quality.

The telescope is compatible with standard 1.25-inch eyepieces, allowing for a wide range of customization options. Upgrading to higher-quality eyepieces would significantly improve the telescope’s performance.

Aftermarket accessories, such as a better finderscope or a more stable tripod, could further enhance the observing experience. Adding a light pollution filter can improve views in urban areas.
