The ASI 585M Pro It is equipped with a modern 3840 x 2160 pixel sensor. Sony IMX585 sensor It impresses above all with 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 deep-sky photography. The sensor is large enough for many deep-sky objects, so a corrector is usually unnecessary. The camera is ideal for:
- High-resolution detailed lunar and planetary photography
- Solar photograph (with the appropriate filter) with high resolution of details
- Prolonged exposure to nebulae and galaxies
- Infrared photography to reduce atmospheric influences
- EAA on planets, moon and sun
The raw images are already high quality, as the sensor exhibits no magnification flare and the images are very sharp. This is further enhanced by powerful Peltier cooling, which operates up to 35°C below ambient temperature, enabling 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 light to pass through, so you can also take infrared photos with the camera. With the right selection of contrast filters, fog filters, IR passband filters, or UV/IR blocking filters, you'll have complete control over the light reaching the sensor.
Peltier cooling: reduces the sensor temperature
During data acquisition, the sensor heats up. Thanks to regulated Peltier cooling, the sensor remains well-cooled even at high ambient temperatures. Thus, 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 utilizes STARVIS 2 technology in the IMX585 sensor, which ensures excellent low-light performance. It can achieve very high light-gathering capabilities in astrophotography and obtain 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 guarantee a wider dynamic range. Combined with the wide field of view offered by the sensor's large format, the ASI585MC is not only ideal for photographing the sun, moon, and planets but can also be used as a live-streaming camera.
