ZWO ASI183MM Pro cooled mono CMOS camera

ZWO ASI183MM Pro cooled mono CMOS 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 μm pixel size. – able to capture19 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.

Reliable Mechanics

ASI183 Pro has same mechanics as ASI1600 Pro. 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.

Notice: After receiving user feedback, it has been brought to our attention that this IMX183 sensor has grid pattern noise when doing Ha solar imaging. To alleviate this issue, please take flat frames for calibration (out of focus or add a Barlow lens to take flat frames). We recommend our ASI1600/ASI174 mono camera for Ha solar imaging.

Dark Current

The dark current of the ASI183 is extremely low, based on our test results.

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.

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, ASI183MC 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.

*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would also decrease. 

Please notice that the camera needs to be connected to an external 11-15v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-15V to power the camera. If you don’t have one, please click here to buy a 12V power adapter. There are 4 different standards for different countries, please make sure you selected the correct adapter when placing the order.
