Explore Scientific ED APO 127 mm, CF Hex

1. Advanced Apochromatic Design: The Explore Scientific ED APO 127 mm features a three-element apochromatic lens system made with Hoya FCD100 glass, a significant upgrade from standard achromatic designs. This advanced optical configuration virtually eliminates chromatic aberration, delivering stunningly sharp, color-free, and high-contrast images across the entire field of view, crucial for both visual astronomy and professional-grade astrophotography.

2. Carbon Fiber Construction: The telescope's optical tube is crafted from lightweight and robust carbon fiber. This material choice not only reduces the telescope's overall weight, enhancing portability, but also provides superior thermal stability compared to traditional aluminum tubes. This means less image distortion due to temperature changes, ensuring consistent optical performance during long observation or imaging sessions.

3. Precision HEX Focuser: Equipped with Explore Scientific's 2.5-inch HEX Focuser, this refractor offers unparalleled focusing precision. Its innovative hexagonal rack and pinion design ensures a completely sag-free drawtube, even with heavy imaging equipment attached. The included 10:1 dual-speed mechanism allows for both rapid adjustments and micro-fine tuning, essential for achieving critical focus in high-resolution photography and viewing.

4. Versatile Application: As an apochromatic refractor telescope, the ED APO 127 mm is engineered for versatility. It excels in diverse astronomical applications, from detailed planetary and lunar observations to capturing deep-sky objects like nebulae and galaxies with exceptional clarity. Its premium optics and robust construction make it a top choice for serious amateur astronomers and astrophotographers seeking high-performance equipment.

ABOUT THE EXPLORE SCIENTIFIC ED APO 127 MM, CF HEX

The Explore Scientific ED APO 127 mm, CF Hex distinguishes itself from other models in its series through its combination of a larger aperture, advanced apochromatic optics, and a hexagonal focuser, tailored for superior performance. This precision instrument features a 127 mm (5-inch) air-spaced triplet optical design with Hoya FCD100 Extra-Low Dispersion (ED) glass. This eliminates virtually all chromatic aberration, delivering exceptionally crisp, high-contrast, and color-free images, making it ideal for both critical visual observation of planets, the Moon, and deep-sky objects, as well as high-resolution astrophotography. Its carbon fiber (CF) tube construction ensures superior thermal stability and significantly reduces overall weight, enhancing portability without compromising optical performance. The integrated 2.5-inch HEX Focuser offers smooth, precise, and sag-free focusing, crucial for maintaining optimal image quality, especially during long-exposure imaging sessions. This type of construction, an apochromatic refractor, is intended for discerning astronomers and astrophotographers who demand uncompromising optical clarity and robust mechanical stability for capturing the finest details of the cosmos.
