The Vixen SXD2WL‑SD103S (ES25037) combines a high-performance SD-glass apochromatic refractor tube (SD103S), a motorized equatorial mount with wireless GoTo control (SXD2WL), and a stable adjustable tripod — ideal for both visual observation and astrophotography. The SD103S optical tube delivers crisp, high-contrast, low-aberration views thanks to its SD glass and multi-coated optics, while the 795 mm focal length (F/7.7) offers a versatile balance for detailed planetary views or wide-field deep-sky observations. The flip-mirror diagonal allows quick switching between eyepiece viewing and camera imaging. With the wireless mount, you can control slewing and tracking from a smartphone or tablet — making setup and operation smoother than ever.

Key Features:

  • SD 103 mm Apochromatic Objective — SD-glass lens with multicoating reduces chromatic aberration, delivering sharp, color-accurate views of planets, nebulae, clusters, and galaxies.

  • Balanced Optics (795 mm, F/7.7) — Great balance between magnification and light-gathering power for both planetary detail and deep-sky objects.

  • Flip-Mirror Diagonal & Versatile Back-End — Switch instantly between visual observation and camera imaging; accepts 60 mm/42 mm T-rings, or 50.8 mm / 31.7 mm eyepieces.

  • Wireless GoTo Equatorial Mount (SXD2WL) — Control the mount via smartphone/tablet: enjoy automatic object selection, slewing, and tracking.

  • Ready-to-Use Kit — Includes optical tube, mount, tripod, eyepieces (SLV20 mm & SLV5 mm), finder, weights, flip mirror, and more — everything needed for immediate observation or astrophotography.
