Explore Scientific ED APO 127mm f/7.5 FCD-100 Alu HEX is a high-class optical tube designed mainly for use in professional astrophotography of deep sky objects. This telescope can also be successfully used as an instrument for visual observations, guaranteeing the highest level of image detail.

This telescope was constructed as a classic apochromatic triplet with an air gap. To ensure the best possible correction of chromatic aberrations, the optical system is equipped with a low dispersion (ED) lens made of Hoya FCD-100 glass, responsible for correcting chromatic aberrations and thus ensuring adequate color reproduction, which is crucial from the point of view of astrophotography. . The highest quality optics is complemented by covering the lenses with an anti-reflective EMD coating, improving image contrast and detail.

The tube works with a solid Hexafoc Deluxe focuser with a diameter of 2.5". Thanks to the internal aperture of the focuser of 65 mm, this instrument is free from the vignetting effect even when using cameras with large full-frame matrices.
