150mm Apochromatic Triplet Refractor for Advanced Astrophotography
The SkyWatcher Esprit 150EDX APO is a premium 150mm apochromatic triplet refractor with a 1050mm focal length (f/7), designed to meet the needs of demanding astrophotographers and experienced visual observers.
Part of the renowned Esprit EDX Super APO series, this optical tube assembly combines high-end optical performance with precision mechanical construction, delivering performance comparable to top-tier apochromatic refractors.
ED Triplet Optics with Ohara FPL-53 Glass
The air-spaced ED triplet design incorporates premium Japanese Ohara FPL-53 glass, ensuring exceptional chromatic correction and superior color fidelity.
All air-to-glass surfaces are treated with Metallic High-Transmission Coating (MHTC), achieving up to 99.5% light transmission for bright, high-contrast images.
- Outstanding contrast and sharpness
- Minimal chromatic aberration
- Natural color reproduction
- Excellent for Moon, planets and deep-sky objects
Optimized for Full-Frame Astrophotography
The f/7 focal ratio offers an ideal balance between field of view, image scale and brightness. An optional 0.77x reducer/field flattener with M48 photographic connection provides a perfectly flat field even for full-frame sensors.
The robust mechanical structure supports heavy imaging setups, including large cameras and filter wheels, without flexure or focus shift.
Professional 3” Dual-Speed Rotatable Focuser
The CNC-machined 3-inch rotatable dual-speed focuser with 1:11 micro-reduction ensures precise and stable focusing performance.
- High load capacity
- Smooth and backlash-free focusing
- Integrated scale
- Adapters for 2” and 1.25” accessories included
- Improved field illumination compared to standard focusers
Mechanical Design and Portability
The retractable dew shield reduces transport length while maintaining optimal dew protection during observation.
A solid carry handle integrated into the tube rings allows secure and ergonomic handling. The telescope is supplied in a custom aluminum hard case for safe storage and transport.
