Vixen AX103S Refractor Telescope

The Vixen AX103S, f/8.0 Refractor features a three element objective lens, incorporating a central ED lens.

This reduces chromatic aberration and yields high contrast images. The rear Field Corrector Lens, helps to deliver sharp images to the edges of the field of view.

"Precision Multi-Coating" is applied to every lens surface and guarantees extremely high light transmission, whilst its outstanding optics allow for high magnification observation.

The chromatic aberration on the visible spectrum and spot diagrams deliver remarkable color correction and crisp sharp images. Star images are less than 20 microns on the edge of the imaging field.

The built in Dual Speed Focuser enables coarse and fine focus adjustments. Sky at Night Magazine states: "With its excellent build quality and rich feature set, we thoroughly recommend this system if you’re looking to upgrade from your current setup". Read the full review.
