CAMERA ASI6200MM P25 PRO SERIE

CAMERA ASI6200MM P25 PRO SERIE

Description

The CAMERA ASI6200MM P25 PRO SERIE from ZWO is a next-generation cooled astronomy camera.
Equipped with the Sony IMX455 full-frame CMOS sensor, it delivers 9576×6388 resolution (61.2 MP), native 16-bit ADC and high dynamic range equivalent to 14 exposure levels, ensuring detailed and natural images.

The P25 series differs from the previous model with a 512 MB DDR3 buffer, improved long-exposure stability and optimized thermal design.
Its dual-stage TEC cooling reduces sensor temperature by over 35 °C below ambient, lowering dark current to only 0.0017 e/s/pix at 0 °C.
It also includes a built-in anti-dew heater and precise sensor adjustment via three screws.

Quantum efficiency reaches 91 % (MM) and 80 % (MC). At only 0.7 kg, the CAMERA ASI6200MM P25 PRO SERIE is compact, reliable and the perfect choice for professional astrophotography in full-frame 24×36 format.

ASI6200MM/MC Pro uses Sony’s back-illuminated IMX455 Full Frame format native 16-bit ADC sensor. It has3.76µm, ultra-low 0.86e readout noise and an innovative breakthrough resulting in zero amp-glow.

Note：

External power supplies are needed for all ASl-cooled cameras. We recommend you use a 12V@3A~5A DC adapter (D5.5×2.1mm, center pole positive) or a lithium battery with 11-14V to power the camera. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.

 

ASI6200MM Pro Sensor

Six Unmissable Advantages

Appreciation Work

Exquisite Craftsmanship for a Premium Imaging Experience

 

1. Meticulous design, uncompromising quality.

The body weighs just 0.7 kg（1.54 lbs）, yet delivers outstanding image performance.

 

2.Zero Amp Glow – worry-free imaging even with long exposures and high gain.

The ASI6200MM/MC 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.

3.Anti-dew

ASI6200MC 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.

 

 

Extraordinary performance captures the beauty of the universe

 

1.Full Frame format
The ASI6200 Pro camera uses a full-frame format. The outstanding 9576×6388 resolution provided by the onboard Sony IMX455 sensor makes this camera a 61.2-megapixel full frame powerhouse! The sensor length and width are 36mm x 24mm respectively, and the diagonal is 43.3mm. This is a camera with a small pixel size of 3.76um that can accommodate a large well depth of 51.4ke.

 

2.Native 16bit ADC
ASI6200 Pro camera is our first batch of CMOS astronomy cameras with true 16-bit ADC. It is not a CCD-style 16-bit ADC – it really can achieve a dynamic range output of 14 stops. This significantly improves the image sharpness and contrast, and the contrast gradients are smoother and more natural-looking.

3.Two-stage TEC cooling, ultra-low dark current
Thanks to the two stage TEC cooling, ASI6200 Pro 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 T 35℃ is tested at 30℃ 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.

Practical features for effortless astrophotography

 

1.USB3.0 & 512M DDR3 Memory
The ASI6200 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.

*ASI Cooled Cameras produced after August 2023 have changed their DDR3 buffer from 256MB to 512MB.

2.Three sets of screws
The sensor is adjusted by three sets of screws, enabling precise calibration. (Each set consists of a push-pull screw pair.)

Camera Performance: Low readout noise, high dynamic range

The ASI6200MM/MC 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 colour gradients look smoother and more natural-looking.

The innovative design of the ASI6200MM Pro also includes high conversion gain mode (HCG) that automatically kicks in at a gain setting of 100, reducing the amount of read noise while simultaneously preserving the dynamic range during high gain imaging.

QE value

The QE peak value of the ASI6200MM Pro camera is 91%.

Quantum Efficiency（ASI6200MM Pro） 

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 0.0017e/s/pix. This means a 300s exposure will only cause a dark current noise of 0.51 e/pix, which is completely negligible!
