The AXD2‑AX103S‑P combines a high‑performance 103 mm SD apochromatic refractor with the robust, Go‑To capable AXD2 equatorial mount — delivering a full-featured telescope system ideal for serious astrophotography and dedicated stargazing. The optical tube (AX103S) uses a triplet SD‑glass design with advanced multicoating, producing crystal‑clear, high‑contrast images with minimal chromatic aberration and sharp star images across the field — even at the edges.
Mounted on the AXD2, this system offers smooth, stable tracking via its micro‑step motor drive and 21‑bearing super‑alloy axes. The included computerized controller with star‑chart Go‑To navigation makes locating and centering celestial objects simple, while the built‑in polar alignment scope ensures accurate alignment for long‑exposure imaging. Supplied counterweights, dovetail mounting hardware, and the included pillar/tripod base complete the package — giving you a ready-to-go, high‑luxury astronomy rig straight out of the box.
Whether you’re photographing deep‑sky objects, tracking planets, or observing faint nebulae and galaxies, the AXD2‑AX103S‑P offers optical quality, mechanical stability, and ease of use to satisfy both advanced astrophotographers and serious visual observers alike.
