About Explore Scientific ED127

Are you an astrophotography enthusiast or a visual astronomer seeking precision and clarity in your celestial observations The Explore Scientific ED127 Essential Series Air-Spaced Triplet Refractor Telescope is engineered to elevate your stargazing experience. This classic model has been meticulously retooled to cater to the exacting demands of astrophotography, ensuring that every cosmic capture is as breathtaking as the last.

The telescope features a newly designed precision front cell with push-pull adjustments, allowing for meticulous tilt and centering modifications. This level of control is essential for achieving optimal collimation, resulting in the sharpest star images possible. The updated 2-inch two-speed rack and pinion focuser, complete with robust locks and rotation adjustment, offers unparalleled stability and precision, enabling you to position and secure your imaging system with confidence.

Portability has been enhanced with the addition of a new retractable dew shield, making the telescope more compact and easier to transport to your favorite stargazing locations. The ED127 is not just about technical advancements; it's a proven performer that consistently delivers for both astrophotographers and critical visual astronomers.

At the heart of the telescope's exceptional viewing capabilities is the use of genuine HOYA FCD1 ED glass, renowned for its ability to minimize chromatic aberrations. This high-quality extra-low dispersion (ED) glass, combined with proprietary EMD enhanced multi-layer coatings on all optical surfaces, ensures that you'll witness the cosmos with brilliant high-contrast images, whether you're exploring the intricate lunar landscape or distant galaxies.

The air-spaced triplet optical design is a testament to Explore Scientific's commitment to quality, virtually eliminating chromatic aberrations and providing true apochromatic performance with diffraction-limited optics. This means that whether you're observing the distinct bulging center of the Sombrero Galaxy or the spiraling grandeur of the Pinwheel Galaxy, the ED127 will reveal the universe's treasures in stunning detail.

The telescope's cradle rings are not only designed for secure mounting but also feature a built-in handle, sculpted for comfortable and safe handling. The handle's top face is slotted to accommodate a 1/4x20 bolt, allowing for easy attachment of a DSLR camera for "piggyback" imaging. Additionally, the bottom of the cradle ring is equipped with a V-block (Vixen-style) plate, ensuring seamless attachment to your equatorial mount.

To further enhance your observational setup, the telescope comes with the Explore Scientific 2N1 Finder Scope Base pre-installed, ready to accept a finder scope (sold separately) for precise aiming and navigation of the night sky.

Embark on a journey through the cosmos with the Explore Scientific ED127 Essential Series Air-Spaced Triplet Refractor Telescope, a sophisticated instrument designed for those who demand the very best in their astronomical adventures.
