The ASI2600MM Duo combines imaging and guiding sensors in one compact body. The main sensor is the Sony IMX571 sensor with a native 16-bit ADC, 14 stops dynamic range and 3.76 µm square pixels. The readout noise is as low as 1.0e and the full well capacity reaches an incredible level of 73ke. And on top of all this it has no amp glow!

The guide sensor is the type 1/1.8 SC2210 with excellent NIR sensitivity. The sensor size is 7.68mm x 4.32mm. It has 4µm x 4µm pixels with an array of 1920 × 1080 and a full depth of 8780e. The stars on the corner of the guide images affected by reducers back focus distance might not appear very round however this is not due to the sensor tilt and it will not affect normal use.

Two-in-one design:
Thanks to the compact design, the ASI2600MM Duo only needs one USB cable for control. It reduces potential cabling issues and improves setup speeds. You don´t need a separate OAG and guiding camera.

The main sensor:
The main sensor which is the IMX571 features an APS-C format & 26MP total pixels. The size of the sensor is 23.5mm in width x 15.7mm in height, and the diagonal is 28.3mm. The 3.76µm x 3.76µm small pixel size accommodates an impressive full depth of 50ke and with the new hardware technology, it can even be extended to 73ke.

Guide sensor:
The SC2210 sensor was taken from the ASI220MM Mini camera and features very high sensitivity. The QE peak value reaches 92% at 500nm and the readout noise is as low as 0.6e. As this is a new generation of guide sensor, it has achieved great results in guiding, proven by hundreds of astrophotographers worldwide.

The USB 3.0 cable operates both sensors (Main and Guide sensor). The guide sensor can then be selected in PHD2, for example, and the IMX571 sensor in the imaging software that you are using.

Special Features:

STARVIS technology:
ASI2600MM DUO is based on Sony's STARVIS technology. Sony's back-illuminated CMOS image sensor improves sensitivity and noise reduction - the key factors to enhancing image quality.

Native 16bit ADC:
This 16-bit ADC is not a CCD 16-bit ADC. It can really achieve a dynamic range output of 14 stops, which will significantly improve the image sharpness and contrast, and also create smoother and more natural color transitions.

FPS:
ASI2600MM Duo's max FPS in RAW 8 mode at full resolution is 15 fps.

Extended full well mode:
The full well capacity of ASI2600MM Duo is extended to 73ke.

USB 3.0 & 512 MB DDR3 buffer:
With the use of the USB 3.0 cable and 512MB DDR3 buffer, ASI2600MM Duo provides a stable and secure data transmission that can effectively avoid frame-dropping issues during long exposures.

No amp-glow:
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images. This is the tell-tale sign of amp glow. As the ASI2600MM Duo uses zero-amp glow circuitry so you won´t have to worry about amp glow even when using high gain, long exposure imaging.

QE (Quantum efficiency):
Based on ZWO's testing results, the QE peak value of ASI2600MM Duo is over 91%.

Two-stage TEC cooling:
Thanks to the two-stage TEC cooling, ASI2600MM Duo can lower the CMOS 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 T35 °C is tested at 30°C ambient temperature. It might reduce downwards when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would also decrease.

Dark current noise:
The dark current noise of the ASI2600MM Duo is extremely low. Even with moderate cooling, you get a very low-noise image.

Anti-Dew heater:
There is a polyimide heater completely fitting the protective window in the ASI2600MM Duo camera. It can help avoid any potential annoying dew or icing issues depending on the environment in which you capture images. The power of the heater is around 5W. You are free to turn it off anytime in your photography software if you want to save power.

Important: external power supply required!
This camera requires a 1 amp power supply even during uncooled operation, which can be a problem for USB ports on computers, because they are generally only rated for 900 mA (0.9 A). Stable operation of the camera is therefore only possible with an external 12V power supply.

Practical Storage advice: 
Storage of cameras and accessories, especially in our latitudes, the nights are often very humid. This humidity condenses on your camera, eyepiece or filter when they come into the warm interior of your home after imaging. Cooled cameras are especially affected by this. Good storage is an important prevention mechanism against dew and also extends the life span of your equipment.

After use, put the camera immediately into its Protect Case and ideally add some silica gel. During storage, the silica gel will suck the moisture out of the camera. At the same time, the penetration of humid room air is prevented. Dry storage even allows the small dry tablets in cooled cameras to partially regenerate. Your camera or accessories are always ready for you in optimal condition. Silica Gel is available here:

The cameras are not airtight, so if the camera remains on the telescope, it is exposed to moisture. The small amount of desiccant in the camera can protect the sensor and the inside of the protective glass from moisture for the duration of the exposure, but not for days on end. Moisture problems can be the result. A simple trick is to stretch a plastic bag around the focuser to which the camera is attached so that no air can get in. Silica gel is placed in a small cloth bag inside the plastic bag. This will also create a "dry climate zone" for the camera on the telescope. This allows you to leave the camera on the telescope for a few days for an imaging session lasting several days.

Guiding without ST-4 Port:
This camera has no ST-4 autoguider port, so you have to connect the mount directly to the PC.
