The ZWO FF130 APO is a high-performance 130mm f/7.7 quadruplet refractor designed to meet the needs of astrophotographers and visual observers who demand exceptional optical quality and convenience. With its precision-engineered Petzval optical design, this telescope offers a fully corrected, flat field without the need for additional field flatteners, making it an ideal choice for deep-sky imaging and high-contrast visual observations.
Unlike traditional doublet and triplet refractors that require external flatteners and careful backfocus adjustments, the FF130 APO is optimized from the ground up for astrophotography. The four-element optical system eliminates coma, astigmatism, and field curvature across the entire imaging plane, delivering pinpoint stars edge-to-edge without the hassle of complex spacing calculations. For those who want to focus on capturing stunning celestial images without worrying about additional optical accessories, this scope provides a true plug-and-play experience.
High-Quality Optics with Superior Color Correction
At the core of the FF130 APO is a precision-matched quadruplet lens system featuring two elements of extra-low dispersion (ED) glass. This optical configuration effectively minimizes chromatic aberration, providing exceptional color accuracy and contrast across the entire visible spectrum. The result is images with superb sharpness, enhanced color fidelity, and reduced star bloating, even when imaging bright objects such as the Moon, planets, or globular clusters.
With a focal length of 1000mm, the FF130 APO offers an excellent balance between field of view and resolution, making it well-suited for both wide-field deep-sky imaging and detailed planetary work. The f/7.7 focal ratio provides an optimal balance between light-gathering power and image scale, making it a versatile option for various imaging targets, from nebulae and galaxies to lunar and planetary details.
Designed for Astrophotography
Astrophotographers will appreciate the completely flat 60mm image circle, which ensures uniform illumination and sharp focus across large-format sensors. This feature is particularly important for users of full-frame and APS-C cameras, as it eliminates distortions at the edges of the field that can degrade image quality. The integrated field flattener means there is no need to purchase and install separate flatteners, simplifying the imaging process and reducing potential optical misalignments.
The FF130 APO is equipped with a robust 3.4-inch dual-speed rack-and-pinion focuser, engineered to handle the weight of heavy imaging payloads such as full-frame cameras, filter wheels, and motorized focusers. The large focusing mechanism allows for fine adjustments with smooth precision, ensuring critical focus is easily achieved. The focuser also features a locking mechanism to prevent image shift, maintaining stability throughout long-exposure imaging sessions.
For those using rotators or requiring specific framing of their astrophotography subjects, the focuser assembly is fully rotatable, allowing for easy composition adjustments without disturbing focus.
Exceptional Visual Performance
While the FF130 APO is designed with astrophotography in mind, it also excels as a high-quality visual instrument. The premium apochromatic optics deliver razor-sharp views of planets, the Moon, and deep-sky objects with outstanding contrast and minimal chromatic aberration. Planetary observers will appreciate the crisp, high-contrast details visible on Jupiter and Saturn, while deep-sky enthusiasts will enjoy stunning views of nebulae, star clusters, and galaxies. The telescope's 130mm aperture provides ample light-gathering power for detailed observations, making it a fantastic all-around performer for both visual astronomy and imaging.
Built for Stability and Portability
The FF130 APO is constructed with a precision-machined aluminum optical tube that is both durable and lightweight. The optical tube is equipped with sturdy tube rings and a Losmandy-style dovetail, ensuring a secure and stable mounting experience. The retractable dew shield helps to minimize stray light while reducing the overall length of the telescope for easier transport and storage.
The included mounting rings and dovetail plate are designed for compatibility with most equatorial mounts, providing a stable platform for imaging and visual use. Whether you're setting up in a backyard observatory or traveling to dark-sky locations, the FF130 APO offers the durability and convenience needed for any observing session.
