SVBONY SV580 80mm f/4.5 Petzval APO Full-Frame Astrograph
Key Features
Professional Petzval APO Imaging Performance
Experience high-resolution astrophotography with a 4-group 6-element Petzval APO design featuring dual ED glass for reduced chromatic aberration and improved star quality.
Simplified Full-Frame Astrophotography Setup
The built-in field flattener supports a 44mm image circle, eliminating the need for an additional flattening accessory and reducing setup complexity.
Faster Capture with f/4.5 Optical Speed
A fast focal ratio improves light-gathering efficiency, helping astrophotographers capture faint deep-sky details more effectively.
Wide Field View for Large Celestial Targets
With a 360mm focal length, SV580 is optimized for capturing expansive nebulae, galaxies, and large deep-sky structures.
Designed for Modern Astrophotography Systems
Compatible with full-frame cameras, APS-C cameras, EAF focusing systems, filters, and guiding accessories for flexible imaging configurations.
Sextuplet Petzval APO — Exceptional Color Correction
4-Group · 6-Element Design · 2×ED Glass
The advanced Petzval APO optical design minimizes chromatic aberration, delivering natural colors, high contrast, and clean star points without purple or green fringing. Dual ED elements, including FCD100 glass, ensure precise astrophotography details.
Fast f/4.5 Optics — Capture More in One Night
80mm Aperture · 360mm Focal Length
The fast f/4.5 optics shorten exposure time, letting you capture more targets with less demand on your mount and guiding. The 360mm focal length is ideal for framing large nebulae and galaxies, while the 80mm aperture reveals rich details.
Full-Frame Ready — Flat Field Across Large Sensors
44mm Image Circle · Built-In Field Flattener
Designed for full-frame sensors, SV580 delivers a flat imaging field with sharp stars from center to edge. The built-in field flattener simplifies your setup while ensuring consistent image quality across 36×24mm and 43.3mm sensors.
FMC Broadband Coating — Cleaner Star Halos, Richer Nebula Contrast
Multi-layer FMC coatings on every lens surface let light pass through instead of bouncing back — so more photons reach your sensor and none return as ghosting or flare. The payoff in the frame: clean halos around bright stars and faint nebula structure with the contrast to stand out from the sky.
Lab-Verified Optics
Simulation and test data confirm what the design promises: MTF stays near 0.9 from center to the 22mm field edge, spot diagrams stay tight at every field position, and all wavelengths focus at the same plane. Vignetting is effectively zero — every ray that enters the scope reaches your sensor, corner to corner.
Dedicated Bracket — Use the EAF You Already Own
The bracket uses standard mounting points and fits mainstream electronic focusers, so automating focus doesn't mean buying a specific brand. Attach it, calibrate once, and your existing focuser is ready for full autofocus runs.
360° Lockable Rotator — Any Angle, Zero Drift
Rotate the camera a full 360° to frame any target at exactly the angle you want — no loosening the tube rings, no re-aiming the mount. Engraved scale markings let you log a favorite framing and repeat it on the next session, while the lock knob holds the camera put all night: zero sag after balancing, zero rotation during imaging.
Fine-Thread Helical Focuser — Critical Focus, Locked In
The fine-thread helical focuser turns smoothly with precise, repeatable steps — the kind of control critical focus demands at f/4.5, where depth of field is razor thin. With 15–20mm of travel it clears filter wheels and off-axis guiders without extra spacers, and once focus is set, the dedicated lock screw holds it rock-steady through hours of long exposures.
Built-In 2" Filter Thread — Simplified Imaging Setup
Install 2" filters directly inside the optical tube for a cleaner optical path with fewer connections. This design simplifies your astrophotography setup while reducing the risk of light leakage.
Dual M48/M54 Camera Interface — Flexible Imaging Compatibility
Featuring both M48 and M54 threaded interfaces, SV580 supports a wide range of DSLR, mirrorless, and dedicated astronomy cameras. Easily connect your preferred imaging equipment with a secure and versatile camera setup.
Precision Engineering & Versatile Flexibility
Precision CNC-machined from solid aluminum for superior rigidity and optical stability, featuring a reversible dew shield for maximum portability and operational flexibility.
Integrated V-style Handle System — Ready for Your Setup
The 10" V-style dovetail plate fits 99% standard V-style saddles and provides a stable mounting platform. The built-in metal handle and side Vixen finder base allow direct attachment of guide scopes and smart controllers without extra mounting rails, keeping your imaging setup clean and organized.
