The Explore Scientific 5X Focal Extender (1.25") delivers powerful magnification for high-resolution views of the Moon, planets, and double stars — without compromising eye relief or visual clarity. Instead of switching to an ultra-short focal length eyepiece, this extender lets you get five times the magnification while using your more comfortable, longer focal length eyepieces.
Perfect for fast telescopes, the 5X extender enhances detail for seasoned observers and astrophotographers alike. Its precision optics are fully EMD multi-coated and edge-blackened to preserve brightness, contrast, and resolution across the field.
Whether you're imaging or observing, this extender is a versatile upgrade that enhances your setup’s performance with sharp, dramatic views at extreme magnifications.
