The Astro-Tech AT152EDT 152mm f/8 Triplet Apochromatic Refractor – A True Lifetime Telescope
For those who demand the best in optical performance and value, the Astro-Tech AT152EDT is the perfect solution. This 6" f/8 triplet apochromatic refractor is designed for serious observers and astrophotographers who want premium optics, excellent color correction, and the versatility to adapt to different imaging and visual setups. With its FK61 and Lanthanum elements housed in a temperature-compensated, collimatable cell, the AT152EDT delivers stunningly sharp, high-contrast images with virtually no chromatic aberration—making it a truly lifetime instrument for those who appreciate refractor performance at its finest.
Premium Triplet APO Optics – Sharp, Color-Free Performance
At the heart of the AT152EDT is its precision-engineered 152mm triplet objective lens, featuring FK61 as the center element and Lanthanum as the rear element. This combination provides:
Exceptional color correction – Virtually eliminates chromatic aberration for razor-sharp views.
Outstanding contrast and clarity – Fully multi-coated optics maximize light transmission.
Precision-collimated, temperature-compensated cell – Ensures peak performance in all conditions.
Whether you're viewing fine planetary detail, resolving deep-sky objects, or capturing high-resolution astrophotography, the AT152EDT’s premium optics deliver results that rival far more expensive telescopes.
A Versatile & Robust Focuser for Visual and Imaging Use
The AT152EDT is equipped with a high-quality 3.7" dual-speed rack & pinion focuser that provides precise, rock-solid focusing for both visual observers and astrophotographers.
98mm of travel with 4” of removable extension – Adjustable back focus (140mm-210mm) to accommodate binoviewers, astro-cameras, and various imaging setups.
Rotatable design – Effortless framing and composition for imaging.
Secure-Lock compression ring – Ensures your eyepieces and accessories stay firmly in place.
Multiple thread options – Compatible with a wide range of imaging accessories (M100x1, M92x1, M68x1 female threads).
Direct Reducer/Flattener Compatibility – The optional 0.72x reducer/flattener threads directly onto the focuser for optimized astrophotography performance.
This level of flexibility means the AT152EDT is equally at home on a mount tracking deep-sky objects as it is being used for high-powered lunar and planetary observation.
Thoughtful Design for Maximum Convenience
Beyond its exceptional optics and focuser, the AT152EDT is designed with user convenience in mind:
Retractable dew shield with locking screw – Minimizes stray light and protects against dew buildup.
CNC-machined tube rings – Lightweight yet sturdy, with a Losmandy-style dovetail on one side and a Vixen-style dovetail/handle on the other for maximum mounting versatility.
Pre-installed Vixen-style finder scope shoe – Easily attach your preferred finder scope or guide scope.
Weighing just 28 pounds, the AT152EDT is a manageable yet powerful instrument, offering a perfect balance between aperture, performance, and portability.
