ZWO ASI585MC Air — Wireless Smart Deep-Sky Camera (Imaging + Guiding + Controller)
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 + smart controller.
- 256GB eMMC: Shoot multiple targets without swapping cards.
- STARVIS 2 Sensor: High sensitivity, wide dynamic range, no amp glow.
- 4K Resolution with clean live stacking and instant 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~−35°C below ambient for clean long exposures.
Effortless Connectivity
Four USB 2.0 ports for focuser, filter wheel and mount; dual 12V power ports; high-speed USB-C for data.

256GB eMMC On-Board Storage
Capture all night with fast, reliable built-in storage, plus support for up to 1TB external USB media.

STARVIS 2 Sensor • No Amp Glow
Upgraded sensitivity and SNR with hardware-level amp-glow suppression for ultra-clean dark frames and stacks.

Dual-Band Wireless Control
External antenna provides stable 2.4G/5G Wi-Fi within typical observing distances. Control via ASIAIR app, ASIStudio, or 3rd-party apps (ASCOM/Alpaca).

Shoot, Stack & Share
Live stacking, one-tap processing and instant sharing from your phone. OTA app updates keep features fresh.

Low Read Noise • High Dynamic Range
HCG mode automatically engages at high gain to suppress read noise (~0.7e) while preserving wide dynamic range.

Peak Quantum Efficiency
Peak QE measured at ~91% (ZWO Laboratory) for excellent sensitivity to faint targets.

Two-Stage TEC Cooling
Typical sensor delta of −30~−35°C vs ambient reduces dark current for long, clean subs.

Power Consumption & Thermal Design

Image Circle & Compatibility
Compatible with telescopes supporting APS-C or larger image circles. For best guide star quality, a full-frame image circle is recommended.
