One of the outstanding features of the ASI183 is the sensational light sensitivity. It has a QE of 84%, due to the Back Illumination technology, and the very low amplifier glow make the camera very well suited for all astronomical applications, but above all for deep-sky astrophotography.

This "single shot" color camera offers several advantages compared with monochrome cameras. Many imagers prefer not to follow through the laborious L-RGB technique for beautiful colored nebula or planetary images. Color cameras offer a the chance to obtain beautiful images in fewer sessions and without having to constantly change filters. Compared to a standard DSLR camera, the ASI183MC offers much higher light sensitivity, a smoother image and much more depth.

Additional Features:

• USB 3.0 for quick download - can also be used with USB 2.0
• DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.
• Powerful Peltier cooling up to 45°C below ambient.
• One of the most light-sensitive CMOS sensors from Sony with 15.9mm diagonal and 20 megapixels
• Extremely high resolution thanks to the 2.4µm pixels - ideal for fast and sharp telescopes like Apos, Hyperstar, Celestron Faststar, fast Newtonian telescopes etc.
• Comes with AR protect window - full transmission also in infrared. If IR should be blocked, an IR block filter is needed.
• Distance T2-thread (female) to camera sensor: 17.5mm
• High sensitivity - QE up to 84% - ideal astronomy camera for dim objects
• 12 bit ADC

Application ranges of this camera:

Deep sky images (nebulae and galaxies): Due to the high sensitivity, nebulae and galaxies are captured after only a few seconds. By cooling down the camera up to 45°C below ambient, the already low levels of noise can be further reduced. By increasing gain (like the ISO setting of DSLR cameras), you can also reduce exposure times to below 30 seconds if necessary

Solar, lunar and planetary images: Extremely short exposure times (due to high sensitivity) freeze the seeing. Through the high resolution of the sensor, many details can be reproduced even at shorter focal length. Video capture is also possible.

Important: An external power supply is required!
Please notice that all ZWO cameras with cooler need to be connected to an external 11-15 V power supply to work. Even when the cooler is not being used the power supply must be used for the camera to be reliably recognized by the software.
