ED80-FCD100 Series Air-Spaced Triplet Refractor Telescope and Field Flattener f/5 to f/7

Description

The Explore Scientific ED80-FCD100 Series Air-Spaced Triplet Refractor Telescope with Field Flattener is a high-performance optical instrument designed for astronomers and astrophotographers who demand crisp, color-accurate views across the entire field of view. At the heart of this telescope is genuine HOYA FCD100 extra-low dispersion (ED) glass, delivering chromatic aberration correction and color fidelity that rivals the renowned Ohara FPL-53 glass. The air-spaced triplet optical design virtually eliminates false color, while proprietary EMD multi-layer coatings maximize light transmission for brilliantly sharp images. Paired with the Field Flattener (f/5 to f/7), this bundle is purpose-built to produce perfectly flat, pin-sharp star fields from edge to edge - ideal for wide-field astrophotography.

With an 80mm aperture and 480mm focal length, the ED80 strikes the perfect balance between portability and optical power, revealing stunning lunar details, planetary rings, and deep-sky objects with high contrast. Weighing just 7.5 lbs, it excels as a grab-and-go visual scope or as a dedicated guide scope alongside a larger imaging rig. Whether you're shooting the Milky Way, tracking deep-sky nebulae, or guiding a heavy payload, this telescope and field flattener combo delivers the performance serious imagers expect.

Key Features

• HOYA FCD100 ED Glass: Genuine extra-low dispersion glass comparable to Ohara FPL-53 - delivers exceptional chromatic aberration correction and true-to-life color fidelity.
• Air-Spaced Triplet Design: Three-element air-spaced optical design virtually eliminates chromatic aberrations for high-contrast, color-pure views.
• Field Flattener f/5 to f/7 Included: Corrects field curvature across the full image circle for tack-sharp stars edge-to-edge - essential for wide-field astrophotography.
• EMD Multi-Layer Coatings: Proprietary coatings optimize light transmission across the optical path for brilliant, high-fidelity images.
• 80mm Aperture / 480mm Focal Length: Versatile optical specs at f/6 that balance grab-and-go portability with sharp planetary and deep-sky performance.
• 2.5" Hexagonal Focuser: Rugged and precise, this focuser supports imaging payloads up to 10 lbs - compatible with heavy camera and accessory setups.
• Lightweight at 7.5 lbs (3.4 kg): Easy to transport, quick to set up, and mountable on a wide range of equatorial and alt-az mounts.
• Vixen Dovetail: Standard Vixen-style dovetail ensures broad compatibility with popular mount systems.
• Dual-Purpose Design: Functions as a standalone visual and imaging scope or as a guide scope alongside larger telescopes in astrophotography rigs.
• Dew Shield Included: Integrated dew shield helps protect the objective lens and reduce stray light during long imaging sessions.
