Product Description
ASI6200MM Pro
Amazing Craftsmanship, Lightweight body, Solid image quality
We have been working hard to reduce the weight of the camera while improving the performance of the camera. After years of technical accumulation and repeated weight loss experiments by ZWO engineers, ZWO finally concentrated the ASI6200 to 0.7KG
Full Frame format
The ASI6200MM Pro uses full frame format, the sensor length and width are 36mm * 24mm and the diagonal is 43.3mm. This is a 62MP camera with a small pixel size of 3.76um that can accommodate a large well depth of 51.4ke.
Native 16bit ADC
ASI6200MM Pro is our first batch of CMOS astronomy cameras with 16bit ADC. This 16bit ADC is not a CCD 16bit ADC, and it can really achieve a dynamic range output of 14 stops. This significantly improves the image sharpness and contrast, and the color changes are smoother and more natural.
IMX455 backlit sensor
Sony’s back-illuminated CMOS image sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.
With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate.
Sony has newly developed a unique photo-diode structure and on-chip lens optimized for back-illuminated structures, that achieves a higher sensitivity and a lower random noise without light by reducing noise, dark current and defect pixels compared to the conventional front-illuminated structure.
Camera Performance
The ASI6200MM Pro has excellent performance with a dynamic range of up to 14stops. When the gain value is 100, the magical HCG high gain mode is turned on, the readout noise is greatly reduced, and the dynamic range is basically unchanged. It is recommended to set the gain to 0 or gain 100 in deep space.
Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell tale signs of ‘amp glow’. As the ASI6200MM Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
With amp glow – exposure 300 second exposure
ASI6200 frame with no amp glow – Exposure 300 seconds
Anti-dew
ASI6200MM 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.
The heat anti-dew heater power is around 5W and can be turn off in software to save power.
QE value
We suppose that the QE peak value of the ASI6200MM Pro is above 80%.
Two-stage TEC cooling, ultra-low dark current
ASI6200MM Pro uses two stage TEC cooling that can lower the CMOS sensor temperature to more that 35c below ambient, which can greatly reduce dark current generation and sensor noise even with extended exposure times.
The unique dark current suppression technology can even further reduce dark current noise.
At a cooling temperature of 0 °, the dark current noise is only 0.003e/s/pix. Which means 300s exposure can only cause 0.9e dark current noise, which is completely negligible!
Note：ASI6200 Pro camera requires 1A current from the USB, if your PC can not provide enough current, please use an external 12V power supply to power the camera .
USB3.0 & 256M DDR3 Memory
The ASI6200MM Pro is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission. Under long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.

Fabrizio – :
Hi. Another question. I’m building the calibration frames library for the camera. I have noticed that the bias frames are particularly flat. They do not seem to contain much information at all. Does this mean that bias frames are not required for this camera and I can avoid them altogether ? Thanks.

Katherine Tsai – :
Bias cannot be avoided.

Hi. I have noticed that by connecting the camera with the ASCOM driver, the gain is limited to 100 while I know that the max gain should be around 400 or even more. Can you comment on that ? Is it a bug ? Will it be fixed ? Thank you.

Katherine Tsai – :
Do not worry. It is not a bug.
We limit the gain in 0-100 in DSO imaging which is enough for using.

hello, what’s the Current wait time on time on getting this camera shipped if I would buy today (for example) ?

Why you don’t include M54-M54 thin adapter in the package ? M42 and M48 adapters will limit 43mm diagonal of this sensor and produce severe vignetting !

Katherine Tsai – :
Most of the telescopes provide M42 or M48 so we consider the most common circumstance.

Will there be a version with an internal filter wheel and do you accept kidneys as payment?

I use ASI1600mm and ASI183mm at the same computer now.. My control program is SGP.
And I’ll buy the ASI6200mm. Then can I use three defferent ASI cameras at the same computer?

Katherine Tsai – :
Yes you can but you need to make sure how many camera does the ASCOM driver support.

Please add a kit of camera+oag+efw, without filters. Many of us have filters already, thanks!

Does this camera have microlens diffraction paterns with bright stars? That would be an important info for me to upgrade my great ASI1600MM-C Pro whom I am very happy with.

steve ruttenberg – :
1. Is there a UV/IR filter? If so, can it be removed? Need camera with no UV/IR filter or AA filter installed.
2. What is the spectral response? UV to IR?
3. Is this the IMX 455 Sony chip?
4. Are the mounting adapters threaded onto it to allow insertion directly into a focusing tube?
5. Appears to be bolted to filter wheel etc. Cannot tell methods of attachment from pictures shown. Do you have a manual for this yet you could send?
6. If this meets my requirements, I will be buying a a mono version and a color version.
