Product Overview The ZWO FF80 Telescope delivers solid performance for astrophotographers seeking a compact, yet capable telescope. Its 600 mm focal length paired with a Petzval-style quadruplet lens system ensures a flat image plane without requiring additional field flatteners. During imaging sessions, the optics provide clear, color-corrected images with minimal chromatic aberration, making it a reliable choice for deep-sky imaging.
Its lightweight body and compact footprint (450–570 mm) allow for convenient transport and fast setup in various field locations. The included dew shield is effective in managing condensation, a critical factor for uninterrupted long exposure work.
The telescope’s 3-inch focuser offers smooth, fine control over focusing, essential for dialing in sharp stars during critical framing. Compatibility with multiple camera thread standards (M76, M68, M54, M48) also enhances its utility across different astrophotography setups.
Performance in the Field Field testing under clear skies revealed excellent image quality, especially when capturing wide star fields and large nebulae. Focus remained stable throughout sessions, and the flat field eliminated the need for post-processing corrections along the image edges. Star shapes were consistent, with minimal distortion across full-frame sensor coverage.
Many users in online astronomy forums commend the FF80 for its ease of use, consistent focus, and optical clarity. While it may not offer the reach of higher focal length systems for small galaxies, it shines in wide-field contexts, making it ideal for capturing expansive nebulae and Milky Way mosaics.
Pros:
- Excellent optical clarity with flat field imaging
- Lightweight and compact, easy to transport
- Integrated dew shield reduces condensation
- Dual-speed 3-inch focuser provides fine control
- Comes with M76, M68, M54, and M48 camera adapters
- Compatible with full-frame sensors (44 mm image circle)
- Suitable for a full-frame sensor
Cons:
- 80 mm aperture may limit performance on extremely faint targets
- Mount and additional imaging accessories not included
Bottom Line The ZWO FF80 Telescope provides a balance of portability, quality, and imaging capability. For astrophotographers who prioritize wide-field imaging and portability, it delivers reliable performance with high-end optics in a manageable size. With its flat field design, 3-inch focuser, and versatile camera adapter options, the FF80 stands out as a cost-effective yet powerful telescope for astrophotography enthusiasts.
