Tecnosky AC 152/900 V2 OTA

Description

Scan expansive star clusters and execute narrowband H-alpha deep-sky imaging with the Tecnosky AC 152/900 V2 OTA large-aperture achromatic refractor telescope. Built with a fast f/5.9 focal ratio, this 152mm (5.98 in) aperture instrument features a 900mm focal length, delivering 0.76 arcseconds Dawes resolving power and reaching magnitude 13.6 for rich-field visual observation and low-power cluster exploration.

The Tecnosky AC 152/900 V2 OTA utilizes an air-spaced Fraunhofer doublet objective with K9 crown and F4 flint optical glass treated with fully multi-coated anti-reflection coatings. Its 800mm retracted aluminum tube features an unobstructed 0% central profile, a generous 180mm backfocus, and a 2.5-inch dual-speed rack-and-pinion focuser with a 360-degree field rotator. Weighing 10.20 kg (22.49 lbs), this 6-inch refractor mounts securely via CNC-machined tube rings, a top handle, and a 44mm Vixen-style dovetail bar.

Key Features of Tecnosky AC 152/900 V2 OTA

Engineered for rich-field deep-sky visual sweeping and narrowband astrophotography, this 152mm Tecnosky Individual refractor pairs fast f/5.9 Fraunhofer optics with a rotatable 2.5-inch focuser. Its 180mm backfocus and rigid CNC rings ensure versatile camera and diagonal integration without vignetting.
