ED APO 127mm f/7.5 FCD-100 Apochromatic Refractor with HEXAFOC 2.5'' Focuser - Explore Scientific

The Explore Scientific ED APO 127mm f/7.5 FCD-100 apochromatic refractor is designed to provide exceptional optical performance, whether for visual observation or astrophotography. Thanks to its apochromatic triplet with special Hoya FCD-100 glass, it ensures high-level chromatic correction, with a Strehl ratio of 0.97, guaranteeing sharp images free from chromatic aberration.

The lightweight and robust aluminum tube, combined with the HEXAFOC 2.5’’ focuser with a 1:10 reduction ratio, allows for precise focusing, even with heavy accessories and large camera sensors. Its 65 mm clear aperture eliminates vignetting in astrophotography. The f/7.5 focal ratio makes it particularly versatile, allowing for short exposure times to capture fine details of nebulae, galaxies, and planets. This telescope is compact and easy to transport, ideal for amateur astronomers looking for a powerful instrument without compromising portability.
