Product Description

ASI1600MM Pro

DDR Memory Buffer

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

ASI1600 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 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.

We suppose the QE peak value is more than 60%.


Dark Current

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 works 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

ASI1600 Pro has 2 stage TEC cooling system to enable very deep cooling (40°C-45°C below ambient). The cooler requires an external power supply, which is not included with the camera. You may order a suitable power supply from here.

We recommend using a 12V/3-5A or more DC adapter for cooler power supply (2.1×5.5, center positive).
Using a battery with 9-15V is also suitable for the cooler power supply.

    i have an ASI 1600MM Pro mono and i want use it in bin2x mode. Does the Full Well Capacity change compared to the bin1x configuration?

      The full well will *4 since bin2 will merge 4 pixels into 1.

    Hi…I have the opportunity to purchase a 1600mm pro from last year (new in box). Are there any advances in this camera’s manufacturing between last years build and a brand new one today?


    • Avatar


      There is no different.

    would you please build a sensor tilt corrector for the asi1600, like what you have with the other larger sensor cameras ?
    for faster imaging at F5.5 and F/3/6 I have sensor tilt with my brand new asi1600.

      We are working on the new T2-tilter which can be used on cooled cameras.

    Hi, i have asi1600 cooled model B (before pro version). Recently cooler has failure and i wanted to replace. Originally there is sunon maglev 12v/0.8w cooler. Could i use maglev 12v/1.2 instead? Does supply electronics will support this with just little more than original 2A current total?

    Hello now the winter months are almost here i seem to be getting fogging on the inside off the camera,i have read that you don’t open these cameras so what is the best way of removing this moisture thanks.Also if i bought the heater band for this camera how would it fit when i have my filter wheel fitted flush with the camera and not spacer between,so in other words it would be trapped between camera and filterwheel?.

    i have a doubt about the right backfocus concerning my camera ASI 1600ProM fitted on my C14 Edge HD with Hyperstar system.
    The right backfocus for my Hyperstar is 67.4mm whereas for the ASI 1600Pro is indicated the best backfocus of 55mm.
    What should i taken into account?

      Go work as the 67.4mm of Hyperstar

    Does the camera support 14,5 Volt instead of 12? What is the supported voltage range?
