Product Description
ASI585MM adopts Sony IMX585 CMOS sensor. As one of ZWO's latest OSC planetary cameras, it features a large sensor format of 1/1.2", a high resolution of 3840*2160, and a surprisingly amazing characteristic of ZERO AMP GLOW! The pixel size is 2.9um*2.9um. In 12-bit mode, it produces 46.9 FPS with super low readout noise!
8.29MP Sensor
ASI585MM has the same pixel size of the ASI462MC at 2.9um, but its resolution is 4 times that of ASI462MC, which is a total of 8.29 megapixels. The sensor size is 11.13*6.26mm, and the diagonal length is 12.84mm. The 1/1.2" large sensor format makes it very suitable for solar and lunar imaging. It can also be used as an all-sky camera or live camera to observe and monitor cloud cover, rain, meteors and other weather conditions.
Starvis 2
ASI585MM adopts the latest SONY IMX585 sensor with STARVIS 2 technology.
Featuring zero amp glow, lower dark current noise, and 3 times larger full well capacity, this camera is regarded as an upgrade of ASI485. It is also more sensitive to compared to ASI485, especially in >850nm wavelength range, its light sensitivity is 1.5 times greater than ASI485MC (reaching a QE peak of 91%).
Large Full Well Depth
Thanks to the back-illuminated sensor structure and advanced pixel technology, the camera has very low readout noise and a large full well depth (38.7Ke). Especially in low light conditions, the camera performs excellent, capturing very clear images of celestial objects.
Low Read Noise, High Dynamic Range
The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain and allow the camera to maintain the same high dynaic range as it does at low gain. When the gain is 252, the HCG mode is auto-matically turned on and the daynamic range reachs a level close to 12bit.
The readout noise is as low as 0.7e.
