Vixen Telescope SXD2WL-SD103SII

SD103SII Optical Tube Assembly

Improved Spacer for Sharper Star Images

In the previous SD103S model, the objective lens was retained by three small foil clips that served as spacers. Because these clips protruded into the optical path, they produced diffraction, creating three faint radial flares around bright stars. By replacing these clips with a ring-shaped spacer, diffraction is evenly distributed, resulting in beautifully clean and sharply defined star images.

High-Performance SD Glass Lens Minimizes Chromatic Aberration

This high-performance “photo-visual” optical tube employs an SD (Super ED) glass lens that effectively suppresses chromatic aberration. It exceptionally reduces color fringing, enabling clearer, sharper star images.

With an f/7.7 focal ratio and a well-balanced 795 mm focal length relative to its 103 mm aperture, it offers outstanding versatility for a wide range of applications, from detailed planetary observation to astrophotography of nebulae and star clusters.

It comes with a Flip Mirror Diagonal whose mirror can be switched with a simple turn of a dial. This is highly convenient, allowing you to instantly switch between two eyepieces of different magnifications or shift from visual observation to a camera attached to the straight-through back.

It also includes a Vixen-standard dovetail attachment plate and a metal carrying handle, making installation, removal, and transport of the optical tube quick and easy. This setup delivers excellent performance across a wide range of astronomical observing situations.
