The Vixen SXP2‑SD115S is a high-end, all-in-one telescope kit combining a 115 mm SD apochromatic refractor tube, the powerful SXP2 equatorial mount with built-in tracking, and a durable adjustable aluminum tripod (SXG‑HAL130). This set delivers excellent optical clarity, smooth tracking, and a reliable platform for both visual observation and astrophotography — perfect for beginners upgrading to serious astronomy gear as well as experienced observers.
The SD115S refractor uses premium SD‑glass optics to minimize chromatic aberration and produce sharp, high-contrast, true-color views. With a focal length of 890 mm (f/7.7), it offers a balanced optical setup suitable for observing planets, the Moon, star clusters, nebulae, and galaxies. A flip-mirror diagonal enables quick switching between visual viewing and camera imaging, giving flexibility for both lunar/planetary observation and deep-sky astrophotography.
The SXP2 mount features a belt-drive pulse-motor system for smooth, accurate tracking, plus a retractable counterweight shaft and robust construction for stable, vibration-free operation. The included tripod ensures stable support whether you observe from a backyard or take the kit on a trip. This package is designed to get you under the stars quickly — minimal setup, maximum performance.
