About this product
Part Number: ASI1600MM-PRO
New 'PRO' version features a 256MB memory buffer for improved image transfer.
ZWO are well known for their lunar, solar and planetary imaging cameras but the ASI 1600MM, with it’s large (4/3” diagonal) cooled sensor, is aimed at deep-sky imagers.
Imaging with CMOS sensors requires a different approach to traditional CCD sensors, tests suggest more frames / shorter exposures work better than less frames / longer exposures. This takes advantage of the CMOS sensor's very low read noise and stacking more frames suits the type of data CMOS sensors produce (12 or 14-bit, rather than the 16-bit we are used to).
From a practical point of view the ASI1600’s large sensor means those using 1.25” filters will need to mount them as close to the sensor as possible. Flat frames can be used to even out uneven illumination at the frame edges.
Includes an M42 extender ring that, when removed, shortens the back focus distance to only 6.5mm.

- Compatible with Windows / Mac OS / Linux
DDR Memory Buffer
ZWO Pro cameras feature a 256MB DDR3 memory buffer to help maintain data transfer stability and reduce amp-glow issues caused by the slow data transfer speed when using a USB2.0 port.
All ZWO cameras include a 2-year warranty.
Camera Field of View Simulator
The ASI1600 Pro offers very good astrophotography performance - low read noise, low dark current and high dynamic range.
Proposed QE peak value is more than 60%.
Reliable Mechanical Structure
The ASI1600 Pro uses 4 screws to seal the internal chamber - this has been fully tested and is very stable.
Even under high humidity conditions the ASI1600 performs well with no dew problems.
USB 3.0 Port & USB2.0 Hub
USB 3.0 Port: Provides 5Gb bandwidth to make it possible for the ASI1600 Pro to run at 14.7 fps (12bit, normal mode) or 19 fps (23bit, high speed mode) at full resolution (11.7Mega).
We recommend a 12V DC adapter capable of 3A~5A or more for the cooler power supply (2.1*5.5, center positive). A battery from 9-15V is also suitable for cooling power supply.
USB 2.0 HUB: Can be used to connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can manage your cables better with the USB2.0 hub. There are 2 short 0.5m USB2.0 cables supplied with the ASI1600 Pro. The hub can provide power from the external power supply if used.
The ASI1600 Pro has a 2-stage TEC cooling system to enable cooling down to 40-45°C below ambient. An external power supply is required to run the cooler which is not supplied.

The build quality of the camera is good. The camera is very very low noise and its immediately apparent in the detail gathered even while framing targets using very short subs. The sensor is large for the price point but still allows for use of 1.25 inch filters. The only reason I give 4 stars and not 5 stars is the distracting micro lens diffraction pattern caused by the lack or AR coating on the integrated sensor cover glass. A problem common to other cameras using this sensor type. All in all I highly recommend the ASI1600mm pro.

I have used a DSLR for astrophotography for years. Decided to take a leap and go for a dedicated mono cooled CCD/CMOS camera. Only tried it for moonshots so far but wow what a difference. The image quality is superb. Cant wait to try LRGB and Narrowband imaging when then skies get darker.
