ZWO ASI2600MM DUO [MONO] is backordered and will ship as soon as it is back in stock.
The ZWO ASI2600MM DUO combines both imaging and guiding sensors into the one body. The main imaging sensor is the monochrome back-illuminated Sony ExMor IMX571 APS-C with a QE up to 80%, a bit rate of 16 bits, an ultra-high 14 stops dynamic range and ultra-low 1.0e readout noise. Using the latest hardware, full well capacity is extended to 73ke-. Plus, no amp glow!
The guide sensor is the SC2210 Type 1/1.8 (the same sensor used in the ASI220MM Mini) with excellent NIR sensitivity, 4µm pixels in an array of 1920 x 1080 at 7.68 x 4.32mm, and full well depth of 8780 e-. With an exceptional QE peak of 92% at 500nm and readout noise as low as 0.6e-, it is the perfect sensor for guiding behind light pollution filters.
Note: as it is effectively a built-in OAG, the stars visible to the guide sensor may appear distorted. This will not affect normal use.
Thanks to its compact design, the ASI2600MM DUO only requires one USB cable for control, reducing potential cabling issues. No separate OAG and guide camera are needed.
Sony’s back-illuminated CMOS technology improves sensitivity, minimizes noise, reduces power consumption and increases data download speed. In a conventional front-illumination structure, the interconnection of metal wiring and transistors are above the photosensitive silicon surface (photo diode), reducing the overall sensitivity and therefore the quantum efficiency. In back-illuminated sensors, the photosensitive surface is placed on top of the wiring so the incoming light is not obstructed, resulting in a greater quantum efficiency. Sony has developed a new and unique photo-diode structure and an on-chip lens that is optimized for back-illuminated structures, achieving a higher sensitivity and a lower random noise.
The ASI2600MM DUO features a 16bit ADC that can achieve a dynamic range output of 14 stops. This improves the image sharpness and contrast significantly and the colour shades are smoother and more natural.
When the gain value is 100, the HCG high gain mode is automatically activated and the readout noise is greatly reduced while the dynamic range basically remains unchanged.
The ZWO ASI2600MM DUO incorporates a 512MB DDR3 memory buffer that improves data transfer reliability and it minimizes amp-glow caused by slow data transfer speeds.
The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 3.51fps at full resolution (26 Megapixels).
The USB 2.0 Hub allows to connect 2 USB controlled accessories such as a filter wheel, a guiding camera or an electronic focuser, reducing the amount of cables that run directly from your computer.
The 2 stages TEC cooling system allows a ΔT of 35°C below air temperature.
Note: All cooled ZWO cameras require an external power supply of 12V at 3-5A with a 2.1×5.5 mm connector (positive tip).
The dew heater avoids the problem of dew condensation on the optical window of the sensor. The heater can be turned off via software. The power of the heater is 5W.
Traditional CMOS sensors produce a weak infrared light source that is often seen in the corner of uncalibrated images as bright glow. The ASI 2600MM uses the zero amp glow circuit that averts this artefact in your images.
