ZWO has launched its latest offering for the astrophotographers’ community. The ASI585MC Air is a compact, all-in-one camera designed for deep-sky and planetary imaging. It combines a high-sensitivity imaging sensor, a guiding sensor, and a smart controller into a single device, eliminating the need for a separate laptop or external control system. This integration simplifies the imaging setup and enhances portability.
Imaging sensor
At the heart of the ASI585MC Air is the Sony IMX585 1/1.2″ color CMOS sensor featuring STARVIS 2 technology. This sensor offers:
- Resolution: 3840×2160 (8.3MP)
- Pixel Size: 2.9μm
- Quantum Efficiency (QE): Peak value of 91%
- Full Well Capacity: 40ke-
- Zero Amp Glow: Ensures clean images during long exposures
The STARVIS 2 technology enhances sensitivity, especially in low-light conditions, making it suitable for capturing faint celestial objects.
Guiding sensor
The camera includes a built-in SC2210 monochrome guide sensor with 2.07MP resolution. This feature enables seamless auto-guiding without the need for additional hardware, ensuring accurate tracking during extended exposure sessions.
- Resolution: 1920×1080 (2.07MP)
- FPS: 8.5 at full resolution
- Quantum Efficiency (QE): 92%
Live stacking and post-processing capabilities
The ASI585MC Air supports live stacking during imaging sessions, allowing you to adjust brightness, contrast, and other parameters directly on the final image through the ASIAIR app. This feature streamlines the post-processing workflow and allows for immediate assessment of captured images.
Onboard computing and storage
The ASI585MC Air is equipped with:
- Storage: 256GB high-speed eMMC (138MB/s read, 112MB/s write)
- Processing: Built-in controller for image capture, processing, and storage
This onboard computing capability allows for image capture, processing, and storage without the need for an external computer, facilitating a more efficient and portable imaging experience.
Connectivity
The camera offers multiple connectivity options:
- Wireless: Dual-band Wi-Fi (2.4GHz and 5GHz) and Bluetooth for remote control via the ASIAIR app
- Ports: 4× USB 2.0 ports, 1× USB-C port, 2× 12V DC outputs
These features enable users to control the camera remotely and connect various accessories, enhancing convenience during imaging sessions.
Cooling system
The ASI585MC Air incorporates passive cooling along with a 2.4W heating tube, achieving a temperature differential (ΔT) of 30–35°C. This design reduces sensor noise during long exposures, contributing to higher-quality images.
Ideal use cases
The ASI585MC Air is suitable for a variety of astrophotography applications:
- Deep-Sky Imaging: Capturing galaxies, nebulae, and star clusters
- Planetary Imaging: Sensitivity for detailed planetary images
- Electronically Assisted Astronomy (EAA): Live stacking and real-time image enhancement
- Portable Setups: Ideal for remote or dark-sky locations due to its compact and integrated design
Price and availability
The ASI585MC Air is currently available for pre-order at $799, with shipments expected to begin in early July. It’s also listed on various astronomy retailers, though availability may vary.
The ZWO ASI585MC Air represents a significant advancement in astrophotography technology. Its integration of high-quality imaging, guiding, and processing capabilities into a single, compact device simplifies the imaging process and enhances portability. Whether you’re a beginner looking for an all-in-one solution or an experienced astrophotographer seeking a streamlined setup, the ASI585MC Air offers a compelling option.
Clear skies!
