ZWO ASI 585 MM Mono Astro Camera – uncooled astrophotography
The ZWO ASI 585 MM Mono Astro Camera is a sensitive monochrome camera with high quantum efficiency and no amp glow. It is a good choice whenever high frame rates, a steady image and straightforward operation are more important than active cooling.
What is this camera suited for?
With its Sony IMX585 / ASI 585 MM, it is designed for Moon, planets, solar imaging with a filter, deep-sky imaging and infrared imaging. The uncooled design keeps the camera compact and quick to set up. For long deep-sky exposures, a cooled camera is usually preferable; for the Moon, planets, guiding and many EAA applications, this model is especially practical.
Key features
| Series / sensor | Sony IMX585 / ASI 585 MM |
|---|---|
| Camera type | Mono |
| Cooling | uncooled, passive heat dissipation |
| Typical applications | Moon, planets, solar imaging with a filter, deep-sky imaging and infrared imaging |
| Connection | USB camera with autoguider/ST4 support depending on model |
The camera works with the relevant ZWO software and common capture applications. For solar imaging, use it only with a suitable solar filter mounted in front of the telescope.
CMOS sensor in detail
The ASI 585 MM uses the sensitive Sony IMX585 without a color filter array. It can therefore use incoming light particularly efficiently and is a strong choice for monochrome lunar and planetary imaging, EAA and imaging with red, green, blue, H-alpha or IR filters.

These figures help when choosing the right focal length and imaging method. Especially with small pixels, the actual level of detail depends on the combination of telescope, seeing and image scale. For solar imaging, always use a suitable solar filter mounted in front of the telescope.
