127mm f/7.5 Air-Spaced Triplet ED Apochromatic Refractor

The Explore Scientific 127mm f/7.5 Air-Spaced Triplet ED APO produces a visual experience that is often compared to much larger aperture reflector telescopes. The contrast and resolving power can reveal stunning detail on planets and deep sky objects alike.

The designers of the Air Spaced Triplet ED Apo Series pursued to produce top-quality refractors with lasting value. The optical solution was to provide a traditional air-spaced design mounted in a rugged, adjustable lens cell. This design, shaped from experienced craftsmanship and polished from genuine HOYA™ FCD1 (Dense Fluor Crown) ED (Extra-low Dispersion) glass, a critical element to produce images that refractor afficianados know can only be obtained with a high-quality true apochromat.

The owner of an Explore Scientific ED Apo will appreciate the attention to detail and the standard hardware which includes a precision two-speed focuser, a 2" 99% reflective dielectric diagonal, and a deluxe case. You can be confident that the quality and construction of these telescopes will allow heavy use for many years and are backed with a transferrable Five Year USA Limited Warranty.

EMD™ (Enhanced Multilayer Deposition) Coatings eliminates light scatter and maintains image contrast. Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray light.

All Explore Scientific ED Apochromatic Refractor telescopes include a precision Ten-to-One, Dual-Speed Focuser as standard equipment. The eyepiece holder uses a compression ring to prevent the eyepiece or camera barrel from scoring.

We precision collimate every Explore Scientific telescope at our factory to give optimum performance. Although you may never need to adjust optical alignment, our ED Apos allow for optical centering to collimate the lens elements should the telescope ever require it.

Viewing Comfort and the Preservation of Precious Light

The Two Inch Dielectric Diagonal includes a 1.25" eyepiece holder adapter and dust covers to protect the mirror.
