ASI1600 Pro cameras, another giant leap in 1600 history!
The ASI1600MM Pro is one of the most popular cameras from ZWO. It has gained a reputation as a fantastic camera if you want to get serious about your astrophotography. Some of the highlights include:
- 4/3” format with 3.8 um pixel size– flexible pixel size for many types of telescopes.
- 12-bit ADC – giving high dynamic range of 12.5 stops.
- A solid 20ke- full well capacity– helping to reduce the issue of, for example, saturated stars.
- 16-megapixel sensor with 4656*3520 pixels– plenty of detail can be captured in high resolution.
- Read noise as low as 1.2 e-.

DDR Memory Buffer
DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.
ASI1600MM Pro camera includes a 256MB 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.
Astrophotography Performance
ASI1600 Pro offers very good performance for astrophotography. Low read noise, low dark current, high dynamic range.
ASI1600 has a build-in 12bit ADC but can provide 12.5 stops dynamic range which is even better than KAF8300 due to its super low read noise.
QE Graph
We suppose the QE peak value is more than 60%.
Reliable Mechanical Structures
There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.
Even when used in higher humidity environments, ASI1600 Pro will still work fine without dew problems.
USB 3.0 Port & USB2.0 HUB
USB 3.0 Port: Provides 5Gb bandwidth to make it possible for ASI1600 Pro to run at 14.7 fps (12bit, normal mode) or 23 fps (10bit, high speed mode) at full resolution (16Mega).
USB 2.0 HUB: Can connect with various accessories, including a filter wheel, guide camera or electronic focuser, allowing you to manage your cables better. There are two short 0.5m USB2.0 cables included with the ASI1600 Pro. The hub is powered by the external power supply if you connect one.
Cooling System
Thanks to the two-stage TEC cooling, ASI1600MM Pro can lower the CMOS sensor temperature to more than 40-45 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 40-45℃ 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.
