Product Description
Important: For the following imaging camera models, please use a separate 12V power supply rather than the power hub in the ASIAIR Pro as the hub cannot provide enough amperage to power the camera's TEC coolers: ASI6200, ASI2600, ASI2400, ASI533, ASI071MC
ASI2600MM Pro uses Sony's back-illuminated IMX571 Full Frame format native 16-bit ADC sensor. It has an ultra-low 1.0e readout noise pixels and an innovative breakthrough resulting in zero amp-glow. It delivers an outstanding resolution of 6248×4176 pixels, making it a true 26-megapixel powerhouse. Each 3.76 μm pixel offers an impressive full-well capacity of 73ke, ensuring exceptional dynamic range and image quality.
Fresh New Upgrades!
The new ASI2600MM-P25 Camera includes an upgraded board, allowing for enhanced performance in terms of lower readout noise and higher frame rates. It also now has 512MB of DDR3 Cache. This camera features a tilt plate with three adjustment screws and three mounting screws for precise sensor alignment, ensuring a flat imaging field and consistent star shapes across the entire frame. It also now comes with a premium matte finish, to match your favorite ZWO mounts and accessories!
Exquisite Craftsmanship for a Premium Imaging Experience
Zero Amp Glow – Worry-Free Imaging even with Long Exposures and High Gain
The ASI2600MM Pro features a true "zero amp glow" sensor, delivering exceptionally clean dark frames. Even during long exposures or at high gain settings, astrophotographers can easily capture high-quality images.
APS-C Format
The ASI2600MM Pro camera uses a APS-C format. The outstanding 6248x4176 resolution provided by the onboard Sony IMX571 sensor makes this camera a true 26-megapixel powerhouse! The sensor length and width are 23.5mm x 15.7mm respectively, and the diagonal is 28.3mm. This is a camera with a small pixel size of 3.76um that can accommodate a large well depth of 73ke.
Native 16bit ADC
The advanced CMOS architecture of the ASI2600MM Pro enables a true 14-stop dynamic range. This ensures exceptionally smooth tonal transitions, richer color gradients, and the ability to capture both the faintest details and the brightest highlights within a single frame.
Two-Stage TEC Cooling, Ultra-Low Dark Current
Thanks to the two stage TEC cooling, ASI2600MM Pro can lower the CMOS sensor temperature to 35 degrees Celsius below ambient temperature, which can significantly reduce dark current generation and sensor noise even during extended exposure times
*The Delta T 35°C is tested at 30°C 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.
Sensor Tilt Adjustment
The camera incorporates a tilt plate with three sets of adjustment screws. In combination with the three mounting screws, they enable precise fine-tuning of the sensor plane for accurate alignment with the telescope's optical axis, ensuring a flat imaging field and consistent star shapes across the entire frame.
Other Key Features
- USB3.0 & 512MB DDR3 Memory: The ASI2600MM Pro camera is equipped with a USB 3.0 transmission interface and a built-in 512MB DDR3 cache to ensure stable and secure data transmission.
- Powerful Anti-Dew: ASI2600MM Pro comes with the polyimide heater that can avoid any dew problems. The anti-dew heater which completely fit the protective window will heat it to avoid any dew problems.
- Meticulous Design, Uncompromising Quality: The body weighs just 0.7 kg (1.54 lbs), yet delivers outstanding image performance.
Camera Performance
Low Readout Noise, High Dynamic Range
The ASI2600MM Pro camera has excellent performance with a dynamic range of up to 14 stops that will greatly reduce the issue of overexposed images, and make color gradients look smoother and more natural-looking.
When the gain setting reaches 100, the HCG (High Conversion Gain) mode is automatically enabled, which substantially reduces readout noise while preserving dynamic range. For optimal deep-sky imaging performance, a gain setting of 0 or 100 is recommended.
QE Curve
The QE peak value of the ASI2600MM Pro is 91%.
Ultra-Low Dark Current
The unique dark current suppression technology can further reduce dark current noise. At a cooling temperature of 0°C, the dark current noise is only 0.0022e/s/pix. This means a 300s exposure will only cause a dark current noise of 0.7 e/pix, which is completely negligible!
