Introducing the ASI 183MM camera, featuring the Sony IMX183 chip. This back-illuminated monochrome design provides an astonishing 84% quantum efficiency on the CMOS style chip. The total area of the chips is 1" format allowing for smaller filters to be used without vignetting. However thanks to the 2.4 micron pixel size, this chip boasts 20 mega-pixels of resolution. This camera is ideal for wide-field deep sky astrophotography without undersampling.
This Pro version features a cooler to regulate the sensor temperature down to 45°C below ambient temperature. It also provides a 256mb DDR3 memory buffer which further alleviates any amp-glow issues present on a CMOS sensor.
With a peak QE of 84% (mono), 20.18Mega pixels, 15000e full well, 1.6e read noise, and 256MB DDR3 buffer, the ASI 183MM Pro is the most sensitive ZWO camera yet!
The 183MM Pro has a diagonal measurement of 15.86mm with an Approx. 20.48M-Effective Pixel Monochrome/Color CMOS Image Sensor
