Binorum StarView 66/400 ED f/6.1 OTA Apochromatic Refractor Telescope
Premium Compact ED Refractor for Visual and Photographic Astronomy
The Binorum StarView 66/400 ED f/6.1 OTA is a **compact ED refractor** designed for both visual observation and astrophotography. This high-quality apochromatic refractor combines portability with exceptional optical performance thanks to special ED glass that eliminates chromatic aberration. Weighing only 1.5 kg, it represents an ideal choice for astronomers who need a lightweight and versatile instrument with professional characteristics.
Superior ED Glass Optics
At the heart of the telescope is a high-quality ED lens with a 66mm diameter that provides exceptionally sharp and contrasty images without noticeable chromatic aberration. Extra-low dispersion glass effectively suppresses color fringing that is typical in standard refractors. Anti-reflection coatings ensure high light transmission and accurate color rendition, which you'll especially appreciate when observing planets and the Moon. The 400mm focal length with f/6.1 focal ratio is optimally balanced for detailed observation and wide-field astrophotography of brighter objects.

Professional-Grade Focuser System
The telescope is equipped with a high-quality rack and pinion focuser that ensures stable and precise operation without play. The focuser has a load capacity of up to 8 kg, allowing the use of heavy astro cameras, filter wheels, and other professional accessories. Fine and precise focusing meets the demands of serious **astrophotography**, where every detail matters. The standard 2″ eyepiece drawtube is compatible with all common astronomical accessories.
Robust and Portable Construction
The tube is made from durable metal with black matte internal baffling that minimizes unwanted light reflections. Thanks to its compact dimensions and low weight, the telescope is easily portable and suitable for travel. The Vixen/GP dovetail mounting rail ensures compatibility with common astronomical mounts and tripods. The robust construction withstands regular use and provides long-term reliability.
