ZWO ASI585MC Pro color astro camera with active Peltier cooling is a camera for all astrophotographic applications.

This camera is equipped with a 1/1.2" sensor with 3840x2160 pixels (4K UHD). The modern Sony IMX585 sensor is particularly impressive due to its high resolution (2.9 µm pixels), high frame rate and the complete absence of any amp glow. This makes this camera very interesting not only for planets, the sun and the moon, but also for long exposures (deep-sky photography). The sensor is large enough for many deep-sky objects, yet you can usually manage without a corrector. The ASI585MP Pro is an ideal entry-level camera but also an exciting second camera for dedicated astrophotographers. 

The camera is very well suited for:

• Lunar and planetary photography with high detail resolution
  
• Solar photography (with suitable filter) with high detail resolution
  
• Long exposures of nebulae and galaxies
  
• Infrared photography to reduce the effects of seeing, resulting in a sharper luminance channel
  
• EAA (electronically assisted astronomy) for planets, moon and sun.

This camera is a great alternative to a DSLR and mirrorless camera for deep-sky photography. Even the raw images are of high quality, as the sensor no longer shows any amplifier glow and the images are very smooth and low in noise. Added to this is the powerful Peltier cooling up to 35°C below ambient temperature, which means that low-noise images can be taken even at the height of summer.

Moon and planetary photography:
Thanks to the fine 2.9µm pixels, you can achieve a very high resolution from f/10, which makes the use of Barlow and converter systems superfluous.

EAA (electronically assisted astronomy):
The high resolution, combined with a high frame rate of 47 fps at full resolution (RAW8 format), allows real-time observation not only of planets, but also of the moon and sun due to the relatively large sensor. This means you can observe together in a group - without having to wait until everyone has had a turn!

Anti-reflective clear glass filter protects the sensor from dust:
The clear glass filter prevents dust from penetrating the sensor. It also lets UV and infrared light through so that you can also use the camera for infrared photography. With the right choice of contrast filters, fog filters, IR pass filters or UV/IR blocking filters, you have full control over which light falls on the sensor.

Peltier cooling - reduces the sensor temperature:
The sensor heats up during shooting. Thanks to the controlled Peltier cooling, you can keep the sensor well cooled even at high outside temperatures. At an ambient temperature of 20°C you can cool the sensor down to -15 °C.

Very high sensitivity for short exposure times:
One advantage of the back-illuminated CMOS sensor is the reduced readout noise and improved sensitivity. In particular, Sony uses STARVIS-2 technology with the IMX585 sensor, which ensures excellent visibility in low light. You can achieve a very high light yield in astrophotography and obtain high image quality not only in visible light but also in the near infrared range (to reduce seeing). In addition, the low readout noise and the high full-well capacity ensure a larger dynamic range.

In combination with the large field of view offered by the large sensor format, the ASI585MC is not only ideal for solar, lunar and planetary imaging, but can also be used as a live streaming camera or as an all-sky camera for observing or monitoring weather conditions.

The low noise and anti-amp glow circuit make this Peltier-cooled camera interesting for capturing deep-sky objects such as faint nebulae, star clusters and galaxies.

The HCG mode:
The camera has a built-in HCG mode that can effectively reduce readout noise at high gain while maintaining the same wide dynamic range you would expect at low gain. When the gain is 252, the HCG mode turns on automatically. As a result, the readout noise is only 0.7e-, while the dynamic range can still reach almost 12 f-stops.
