ASI585MC Air is ZWO’s ultra-sensitive, all-in-one smart astro camera. It integrates an imaging sensor, a guide sensor, and a smart controller so you can capture, guide, process and share wirelessly with minimal setup.
Main Highlights
- 3-in-1 Design: Imaging camera, guide sensor and smart controller integrated in one device.
- 256GB eMMC: Capture multiple targets without swapping cards.
- STARVIS 2 Sensor: High sensitivity, wide dynamic range and no amp glow.
- 4K Resolution with clean live stacking and fast sharing.
- I/O Hub: USB-C ×1, USB 2.0 ×4, DC 12V 10A ×2.
- Dual-Band Wi-Fi + Bluetooth: Stable 2.4G/5G wireless control.
- HCG Low-Noise Mode: Read noise down to ~0.7e with high dynamic range.
- Two-Stage TEC Cooling: −30 to −35°C below ambient for clean long exposures.
Effortless Connectivity
Four USB 2.0 ports for focuser, filter wheel and mount; dual 12V outputs; high-speed USB-C for data.
256GB eMMC On-Board Storage
Fast, reliable internal storage lets you capture all night, with support for up to 1TB external USB media.
STARVIS 2 Sensor • No Amp Glow
Upgraded sensitivity and hardware-level amp glow suppression deliver ultra-clean darks and calibrated stacks.
Dual-Band Wireless Control
The external antenna ensures reliable 2.4G/5G Wi-Fi over typical observing distances. Control via ASIAIR app, ASIStudio or third-party software supporting ASCOM/Alpaca.
Shoot, Stack & Share
Live stacking, one-tap processing and instant sharing directly from your phone. OTA updates add features over time.
Low Read Noise • High Dynamic Range
HCG mode automatically activates at high gain to achieve ~0.7e read noise while preserving wide dynamic range.
Peak Quantum Efficiency
Peak QE measured at ~91% (ZWO Lab), giving excellent sensitivity for faint galaxies and nebulae.
Two-Stage TEC Cooling
Typical delta of −30 to −35°C vs ambient dramatically reduces dark current for clean long exposures.
Power Consumption & Thermal Design
Image Circle & Compatibility
Works with telescopes supporting APS-C or larger image circles. For best guide star sampling, a full-frame circle is recommended.
