Monochrome refrigerated camera ZWO ASI2600MM-P DUO with integrated guidance sensor

The guide sensor is a 1/1.8 SC2210 type with excellent NIR sensitivity. The sensor size is 7.68 mm x 4.32 mm. It has 4umx4um pixels with a matrix of 1920×1080 and a total depth of 8780e.

The stars in the corners of the guide images affected by the back focus distance reducers may not be very round. This is not due to sensor tilt and will not affect normal use.

Two-in-one design

Thanks to its compact design, the ASI2600MC/MM Duo only requires one USB cable for control. This reduces potential cabling problems and improves setup speed. You do not need a separate OAG and camera guide.

Tiltadjustment from the rear （Optional）

The 3 points from the rear makes tilt adjustment much easier without the hassle of removing the tilt plate from the camera.

Comparison of performance improvement

Guide Sensor

The SC2210 sensor taken from the ASI220MM mini camera features very high sensitivity. The maximum QE value reaches 92% at 500 nm. The read noise is as low as 0.6e. As a new generation guiding sensor, it has achieved great guiding results, demonstrated by hundreds of astrophotographers.

Main sensor

The IMX571 main sensor has an APS-C format and 26MP total pixels. The size is 23.5mm wide x 15.7mm high, and the diagonal is 28.3mm. The small pixel size of 3.76um x 3.76um accommodates an impressive 50ke total depth. With new hardware technology, this is even extended to 73ke.

STARVIS Technology

ASI2600MC/MM DUO is based on Sony's STARVIS technology. Sony's back-illuminated CMOS image sensor improves sensitivity and noise reduction, key factors in improving image quality.

Camera performance

Native 16-bit ADC

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

FPS

The maximum FPS of ASI2600MC/MM Duo in RAW 8 mode at full resolution is 15FPS, which is even faster compared with ASI2600MC/MM Pro.

Extended full well mode

The full well capability of ASI2600MC/MM Duo is extended to 73ke when the gain value is set to -25.

USB 3.0 and 512 MB of DDR3 buffering

No amp-glow

Traditional CMOS sensors produce a faint infrared light source during operation that is often seen in the corners of uncalibrated images. This is the telltale sign of amp-glow. Since the ASI2600MC/MM Duo uses circuits without amplifier brightness, you will not have to worry about amplifier brightness even when using high gain and long exposure images.

QE (Quantum Efficiency)

According to our test results, the maximum QE value of ASI2600MC Duo is over 80% and the maximum QE value of ASI2600MM Duo is over 91%.

Two-stage TEC cooling

Thanks to the two-stage TEC cooling, ASI2600MC/MM Duo can reduce the CMOS sensor temperature to more than 30-35 degrees Celsius below the ambient temperature, which can greatly reduce dark current generation and sensor noise even during long exposure times.

*Delta T 30-35℃ is tested at 30℃ ambient temperature. It might drop when the cooling system operates for a long time. In addition, as the ambient temperature drops, the Delta T would decrease.

Dark current noise (dark)

Anti-mold heater

In the ASI2600MC/MM Duo chamber, there is a polyimide heater that fits completely into the protective window. It can help to avoid any possible annoying problems of dew or icing depending on the environment in which you capture images.

The power of the heater is about 5W. If you want to save battery, you can always turn it off in your photography software.
