ASI 585 MM Pro Mono Camera

• Powerful monochrome camera with Peltier cooling
• Quantum efficiency of approximately 91%
• No amplifier glow (Amp Glow)
• Starvis 2 technology with backlighting
• Very good value for money

The ASI 585M Pro It is equipped with a modern 3840 x 2160 pixel sensor. The Sony IMX585 sensor It is particularly impressive due to its high resolution (2.9 µm pixels), high frame rate, and the complete absence of annoying amp glow. This makes this camera ideal not only for photographing planets, the sun, and the moon, but also for DeepSky photography. The sensor is large enough for many DeepSky objects, so a corrector is usually not necessary. The camera is ideal for:

• High-resolution lunar and planetary photography
• Solar photography (with the appropriate filter) with high resolution details
• Long exposure of nebulae and galaxies
• Infrared photography to reduce atmospheric influences
• EAA on planets, moon and sun

The raw images are already of high quality, as the sensor exhibits no amplification glare and the images are very sharp. Added to this is the powerful Peltier cooling, up to 35°C below ambient temperature, which enables low-noise images even in the height of summer.

Lunar and planetary photography

Thanks to the small 2.9 µm pixels, very high resolution is achieved from an aperture ratio of f/10, making the use of Barlow lenses unnecessary.

The clear glass filter prevents dust from entering the sensor. It also allows UV and infrared rays to pass through, so you can also take infrared photos with the camera. With the right choice of contrast filters, haze filters, IR bandpass filters, or UV/IR blocking filters, you have complete control over the light hitting the sensor.

Peltier cooling: reduces the temperature of the sensor

During recordings, the sensor heats up. Thanks to regulated Peltier cooling, the sensor remains well cooled even at high outside temperatures. At an ambient temperature of 20°C, it can cool the sensor down to -15°C.

Very high sensitivity for short exposure times

One advantage of the back-illuminated CMOS sensor is its lower read noise and higher sensitivity. Sony specifically uses STARVIS 2 technology in the IMX585 sensor, which ensures excellent visibility in low light conditions. It achieves very high light output in astronomical photography and delivers high image quality not only in visible light but also in the near-infrared range (to reduce seeing). Furthermore, the low read noise and high full-well capability ensure a greater dynamic range. Combined with the wide field of view offered by the large sensor format, the ASI585MC is not only ideal for photographing the sun, moon, and planets, but can also be used as a live streaming camera.
