Founder Optics MARVEL Eyepieces: Ultra-Wide Views, Exceptional Comfort!
Founder Optics takes the popular ultra-wide style eyepiece and elevates it with their own signature enhancements in this MARVEL wide angle series. Featuring a vast 80° field of view (FOV) and premium lanthanum glass, you will love the high contrasted and panoramic observing experience! With 8 elements in 5 groups, this series offers a flat-field and well corrected view of the Moon, planets, or your favorite deep-sky targets.
Looking for something for high-magnification views of lunar craters, planets or compact deep-sky objects? The MARVEL 4 mm 1.25-inch eyepiece boasts a generous 20 mm eye relief. It’s ideal for high-magnification deep-sky observing, while also being suitable for planetary and lunar observing as well. The 1.25-inch barrel is conveniently threaded for M28.5x0.6 visual filter installation! Fully multi-coated, edge-blackened optics serve up max light transmission and knockout contrast, while the pop-down rubber eyeguard shields your eyes from stray light for truly immersive viewing.
Signature Features:
- 80° apparent field of view for immersive views of your favorite targets.
- Large >30 mm eye lens & field stop to create wider, more comfortable views.
- Lanthanum lenses deliver brighter, sharper, color-true images with reduced chromatic aberration.
- 1.25-inch barrel with M28.5x0.6 threads for visual filters.
Optics that Don’t Miss
Including a fully multi-coated lanthanum lens you will see noticeably brighter and sharper visuals, while pesky color and spherical aberration are significantly reduced. All glass elements are fully multi-coated to ensure you enjoy high contrast, image clarity, and natural color rendering.
80° Ultra-Wide Eyepiece Series
If you’re looking for comfort while using higher-magnifications the MARVEL series is for you. The impressive 80° FOV creates a sense of floating in space, known as the “spacewalk”effect! You will get a bigger window to see more of your favorite targets up close and personal. The 20 mm eye-relief and 30.5 mm lens diameter makes these truly enjoyable to use, with minimal strain during long sessions.
Built to Last
5The attractive green-and-black housing is made of aluminum and coated with rubber to make it comfortable to handle. It features a tapered 1.25-inch under-cut barrel to minimize the chance of slippage when not completely secure in the focuser. Note: The barrel of the 1.25-inch MARVEL eyepieces are threaded for M28.5x0.6 filters – in most cases, they should be compatible with standard 1.25-inch filter threads from other manufacturers.
