ZWO ASI585MC USB3.0 Color Astronomy Imaging Camera

ZWO ASI585MC – High Sensitivity Color Imaging for Deep Space and Planetary Enthusiasts

If you’re looking for a highly capable planetary and deep-sky camera that delivers exceptional detail without breaking the bank, the ZWO ASI585MC might just be your perfect match. Built around the advanced Sony IMX585 sensor, this one-shot color camera offers a massive 3840x2160 resolution, high sensitivity, and impressive low-light performance. Whether you're capturing lunar craters in stunning clarity or pushing the limits with deep-sky imaging, this camera delivers results that will make your telescope shine.

Cutting-Edge Sensor Technology

At the heart of the ZWO ASI585MC is the Sony IMX585 CMOS sensor, a 1/1.2” format powerhouse that boasts an impressive 8.3-megapixel resolution. With a pixel size of 2.9µm, this camera strikes the perfect balance between resolution and light-gathering capability, making it an excellent choice for both planetary and deep-sky imaging.

Unlike older sensors, the IMX585 features backside illumination (BSI) technology, significantly enhancing its quantum efficiency. This translates to better signal-to-noise ratios, reduced amp glow, and higher sensitivity in low-light conditions—essential for astrophotographers chasing faint nebulae and galaxies.

Ultra-Low Read Noise and High Dynamic Range

One of the standout features of the ASI585MC is its exceptionally low read noise of just 0.8e at high gain settings. This means you can capture fine details even when stacking short-exposure frames, reducing the need for long integration times. Coupled with a 12-bit ADC and high dynamic range, the camera ensures smoother tonal transitions, preserving details in both the brightest and darkest parts of your images.

Impressive Near-Infrared (NIR) Sensitivity

For astrophotographers who love to push their cameras into the near-infrared spectrum, the ASI585MC delivers outstanding results. With a peak quantum efficiency exceeding 90%, it provides excellent sensitivity across a broad range of wavelengths, making it particularly effective for capturing planetary details in methane bands or deep-sky objects that emit strongly in IR.

Zero Amp Glow for Clean, Crisp Images

Unlike many older CMOS sensors, the IMX585 incorporates zero amp glow technology, eliminating the unwanted background glow that can plague long-exposure images. This means cleaner images straight out of the camera, reducing the need for aggressive post-processing and dark frame calibration.

Fast USB 3.0 and Advanced Cooling Design

Speed matters when capturing fleeting planetary details or live-stacking deep-sky objects. The ASI585MC supports USB 3.0 data transfer, ensuring high frame rates for smooth lunar and planetary imaging. While this camera is not actively cooled, its passive cooling design helps minimize sensor noise even during extended imaging sessions.

Versatile Performance – Ideal for Both Planets and Deep Space

The ASI585MC is more than just a planetary camera. Its high resolution and excellent sensitivity make it an ideal choice for capturing:

• Planets – Detail-rich images of Jupiter’s cloud bands, Saturn’s rings, and Mars’ surface features.
• The Moon and Sun – Crystal-clear lunar landscapes and high-resolution solar imaging (with appropriate filters).
• Deep-Sky Objects – Stacking multiple short exposures to reveal nebulae, galaxies, and star clusters.

Compact and Lightweight for Easy Setup

Measuring just 78mm in diameter and weighing only 126g, the ASI585MC won’t weigh down your telescope or put stress on your tracking mount. Its standard 1.25” nosepiece and M42 thread ensure compatibility with most imaging setups, whether you’re using a refractor, Newtonian, or SCT.

Includes Everything You Need to Start Imaging

The ZWO ASI585MC comes with everything you need to get started right out of the box, including:

• 1.25” nosepiece and M42 adapter for easy telescope attachment
• USB 3.0 cable for high-speed data transfer
• ST4 guide cable for use in autoguiding setups
• Soft dust cap to protect the sensor when not in use

Conclusion – A Feature-Packed Camera at an Incredible Value

With its high-resolution sensor, ultra-low read noise, zero amp glow, and exceptional NIR sensitivity, the ZWO ASI585MC is an outstanding choice for astrophotographers looking for a versatile and powerful camera. Whether you're diving into planetary imaging or experimenting with deep-sky targets, this camera delivers breathtaking results without the premium price tag.
