Explore Scientific ED80 Classic White Air Spaced Triplet, 480mm Focal Length Review

Let’s Dive into Explore Scientific ED80 Classic White Air Spaced Triplet, 480mm Focal Length

The Explore Scientific ED80 Classic White Air Spaced Triplet, 480mm Focal Length is a versatile and portable telescope designed for both visual astronomy and astrophotography. This refractor telescope, manufactured by Explore Scientific, boasts exceptional color correction and sharp image quality thanks to its triplet lens design featuring HOYA FCD100 ED glass. Its compact size and relatively short focal length make it ideal for wide-field observing and capturing stunning images of nebulae, galaxies, and star clusters.

I’ve been searching for a telescope that bridges the gap between visual observing and astrophotography. I needed something portable enough to take to dark sky locations, yet capable of delivering high-quality images. The Explore Scientific ED80 seemed to strike that perfect balance.

Unboxing the ED80, I was immediately impressed with the build quality. The classic white metal tube feels incredibly solid, and the retractable lens hood slides smoothly. The weight felt manageable, hinting at good portability without sacrificing stability.

I considered the Celestron NexStar 8SE and the Orion ED80T CF. The Celestron offers a larger aperture but lacks the apo triplet lens and comes with a GoTo mount that increases setup time in remote locations. The Orion has a similar aperture and lens design to the ED80 but is more expensive, making the Explore Scientific the better value.

My first impression was excitement. The telescope felt like a significant upgrade from my previous equipment, promising sharper images and improved portability for my dark sky adventures.

Real-World Testing: Putting Explore Scientific ED80 Classic White Air Spaced Triplet, 480mm Focal Length to the Test

First Use Experience

My first test was at a dark sky site about two hours from my home, known for its minimal light pollution. I tested it visually on the Andromeda Galaxy and the Orion Nebula, and also attempted some wide-field astrophotography of the Cygnus region. The telescope performed admirably in the cool, clear night air.

The ED80 handled the dewy conditions well, thanks to its retractable lens hood, which minimized moisture buildup on the objective lens. The views were remarkably sharp, and I could clearly see details in the Andromeda Galaxy that were previously imperceptible with my older telescope. The ease of use was also apparent, as the focuser moved smoothly, allowing me to achieve critical focus without much effort.

I was initially surprised by how quickly the ED80 cooled down to ambient temperature. This significantly reduced image distortion caused by thermal currents within the telescope tube.

Extended Use & Reliability

After several months of regular use, the Explore Scientific ED80 has proven to be a reliable and enjoyable telescope. It’s become my go-to instrument for both visual observing and wide-field astrophotography. There are no signs of wear and tear on the tube.

The finish has held up well, even after being transported to several remote locations. Maintenance is minimal, primarily involving cleaning the lens with a microfiber cloth and ensuring the focuser remains smooth. The retractable lens hood keeps dust from settling on the objective.

Compared to my previous experiences with lower-quality refractors, the ED80 is in a different league. The image sharpness, color correction, and overall build quality far exceed anything I’ve used before. It definitely outperforms older achromat designs, especially at higher magnifications.

Breaking Down the Features of Explore Scientific ED80 Classic White Air Spaced Triplet, 480mm Focal Length

Specifications

• The Explore Scientific ED80 Classic White Air Spaced Triplet features an 80mm aperture. This allows for ample light gathering capability for observing a wide range of celestial objects.
• It has a focal length of 480mm, resulting in a fast f/6 focal ratio. This is ideal for wide-field astrophotography and provides brighter images for visual observing at lower magnifications.
• The telescope employs a true APO triplet lens design incorporating HOYA FCD100 ED glass. This minimizes chromatic aberration, resulting in images with exceptional color correction and sharpness.
• A 4-Point Push-Pull Collimatable Cell houses the objective lens, which allows for precise centering adjustments and locks. This ensures optimal optical alignment for peak performance.
• It features a robust metal tube with a classic white finish and includes a retractable lens hood. This reduces stray light and helps prevent dew formation on the lens.
• The Explore Scientific ED80 is equipped with a rotatable HEX Dual-Speed 2.5-inch R&P focuser. This provides smooth and precise focusing, essential for both visual observing and astrophotography. It includes two extension tubes and a compression ring for secure eyepiece or camera attachment.
• It includes a 45mm wide saddle dove plate (Vixen-Style) that can also be threaded to mount on a camera tripod. This offers versatile mounting options for different setups.
• The telescope comes with a 2-inch 99% reflective diagonal mirror with a compression ring and a 1.25-inch adapter. This provides high-quality image reflection for comfortable visual observing.

These specifications matter because they directly impact the telescope’s performance and usability. The triplet lens design ensures sharp, color-free images, while the fast focal ratio makes it suitable for astrophotography. The sturdy construction and smooth focuser contribute to a positive user experience.

Performance & Functionality

The Explore Scientific ED80 Classic White Air Spaced Triplet excels at delivering sharp, high-contrast images with excellent color correction. It’s particularly well-suited for observing wide-field objects such as nebulae, galaxies, and star clusters. The telescope’s functionality is enhanced by its smooth and precise focuser, which makes it easy to achieve critical focus.

The strengths lie in its optical performance and portability, but a potential weakness might be the relatively small aperture for observing faint deep-sky objects. Larger aperture scopes will collect more light. Overall, it meets and even exceeds expectations for a telescope in its class and price range.

Design & Ergonomics

The ED80 features a classic and functional design. The white metal tube feels robust and well-built, and the telescope is surprisingly lightweight for its size. The retractable lens hood is a practical addition, protecting the lens from stray light and dew.

The telescope is user-friendly. There is no significant learning curve associated with its use. The smooth focuser, combined with the adjustable lens cell, makes it easy to achieve optimal image quality.

Durability & Maintenance

The robust metal tube and high-quality components suggest that the Explore Scientific ED80 is built to last. With proper care and maintenance, it should provide years of reliable performance.

Maintenance is straightforward, primarily involving cleaning the lens with a microfiber cloth and ensuring the focuser remains smooth. The aluminum tube is resistant to corrosion and scratches.

Accessories and Customization Options

The Explore Scientific ED80 comes standard with a 2-inch diagonal, a 1.25-inch adapter, and two extension tubes. These accessories provide immediate usability for visual observing.

The telescope is compatible with a wide range of aftermarket accessories, including different eyepieces, cameras, and mounting systems. Its Vixen-style dovetail allows it to be easily mounted on various tripods and equatorial mounts. This is key as the user progresses with their astrophotography skills.
