ZWO ASI183MM Pro 20.2MP USB 3.0 Cooled Monochrome Astronomy Camera

ASI183MM Pro uses Sony's IMX183CQJ-J sensor. With a high QE-value and low provides excellent image quality at an affordable price. Some of the features include:

• 20-megapixel sensor with 2.4 microm pixel size. - able to capture 19 frames/s frame rate in 12-bit mode with high detail
• Very low 6e- readout noise - bringing out more details in your images with improved dynamic range
• Full-well capacity of 15ke- - reduces the risk of oversaturated stars in longer exposures

IMX183CLK-J
This back-illuminated, rolling shutter-type CMOS sensor has a diagonal of 15.86 mm and approximately 20.2 megapixels.

High-Speed and High-Picture-Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors
Designed for astrophotography, the Sony IMX183CLK-J (monochrome) sensors use high-sensitivity back-illuminated structures with high resolution 2.4 microm square pixels. The optical size is 1 inch.

DDR Memory Buffer
The ASI183 Pro camera includes a 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. DDR memory buffer is the main difference between ASI "Cool" and "Pro" cameras.

Astrophotography Performance
The ASI183 cameras has an impressive list of characteristics suited for astrophotography including a large full well capacity of 15000e-, small pixel size, 1.6e read noise @ 30dB, and 12stops dynamic range @ Gain=0. The ASI183 cameras also utilize firmware features to minimize amplifier glow for maximum performance in astrophotography.

Reliable Mechanics
ASI183 Pro has same mechanics as ASI1600 Pro (Not Included). There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable even in demanding environments. Even when used in environments with higher humidity, ASI183 Pro will still work fine without dew problems.

High Speed
Fast FPS and high-speed readout come in handy for many applications in astrophotography such as in:

• Solar and lunar imaging
• As well as for live viewing or electronically assisted astronomy (EAA)
• Real-time focusing
• True lucky imaging of double stars and other small objects
• Planetary imaging of the major planets in the solar system, and much more

10Bit ADC
• 5496 x3672: 19fps
• 3840 x2160: 41.04fps
• 1920 x1080: 80.10fps
• 1280 x720: 117.30fps

12bit ADC
• 5496 x3672: 19fps
• 3840 x2160: 36.12fps
• 1920 x1080: 70.48fps
• 1280 x720: 103.23fps

High QE
Sony's back-illuminated Exmor R technology, giving it excellent Deep Sky performance. ASI183 QE peak reaches a respectable 84%. In Ha channel, QE is still over 60%. Having high QE means that more of the light that enters your telescope and reaches the sensor is actually used. With 84% peak Q.E. and no less than -50% within the visible spectrum, the ASI183 will utilize a high percentage of the light that reaches it, improving your signal quality.

Dark Current
The dark current of the ASI183 is extremely low, based on our test results. Dark frame sample @ Highest dynamic range settings(gain=0), 300s, -10 Degree C, bin1.

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port
Provide 5Gb bandwidth to make it possible for ASI183 Pro to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution (20.18Mega).

USB 2.0 HUB
Can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. The ASI183 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one.

Cooling System
Thanks to the two stage TEC cooling, ASI183MM Pro can lower the sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.

Note: The camera needs to be connected to an external 11-14v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5x2.1mm, center pole positive) or lithium battery with 11-14V to power the camera.
