Product Description
ASI294MC Pro
The ASI294 is the first camera in the world equipped with the latest Sony sensor IMX294CJK.
▶IMX294CJK
Sony 10.71M-Effective Pixel Color CMOS Image Sensor (official description from Sony site), with a diagonal of 21.63mm (4/3 format). ZWO has refined the sensor and remolded it to increase the diagonal to 23.2mm with approximately 11.71M-Effective pixels (4/3 format).
▶High-Sensitivity Type 4/3 CMOS Image Sensor that Supports 4K for Astronomic Cameras and Industrial Applications
The IMX294CJK sensor is the first in-house image sensor for astronomic cameras to adopt the 4/3 format and provides the necessary number of pixels for true 4k output at 120 frames per second (w/ ADC 10-bit output mode, the ASI294MC can run up to 25fps at 4k format when used with USB 3.0). In addition, the use of larger-sized pixels achieves SNR1s (link this to Sony’s page on SNR1s, so people know what it means) of 0.14 lx* which is very close to the value of the ASI224 (0.13 lx*).
▶Exceptional low-illumination performance
Exceptional low-illumination performance of SNR: 0.14 lx is realized by use of a large-size optical system and by expanding the area per pixel to 4.63 µm. This makes the IMX294CJK ideal for astronomic camera market applications that require low-illumination performance.
DDR Memory Buffer
The ASI294MC Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.
DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.
14bit ADC w/ 13 stops DR
The ASI294 has a 14bit ADC unit, allowing it to achieve 13 stops of dynamic range. This is an excellent characteristic for deep sky imaging, which is inherently high dynamic range. At 13 stops, the ASI294 has even more dynamic range than the ASI1600.
HCG Mode
HCG (high conversion gain) mode, which reduces read noise to even lower levels at higher gain without loss to dynamic range, is automatically enabled when the gain setting is 120 or higher. Read noise will drop under 2e-, while dynamic range will remain at 13 stops.
63700e full well, which is 3 times than ASI1600’s capacity. Even bright stars won’t saturate under long exposure.
This camera can achieve higher SNR(signal to noise ratio) with just one single exposure.
Reliable Mechanics
ASI294MC Pro has same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.
Even when used in higher humidity environments, ASI294MC Pro will still work fine without dew problems.
High QE
The IMX294 sensor is a BSI (backside illuminated type) sensor, which has very high QE (quantum efficiency, which we estimate is over 75% peak).
Dark Current
The dark current of the ASI294 is slightly higher than the ASI1600, based on our test results.
Dark frame sample @ Highest dynamic range settings, 300s, -10°C, bin1. Please check the dark frame to make sure you fully know the performance.
USB 3.0 Port & USB2.0 HUB
USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI294 Pro to run at 16 fps (14bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution(11.7Mega).
Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 9-15V. Buy the power supply from Bintel too!
Using a battery 9-15V is also suitable for the cooler power supply.
USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. The ASI294 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one.
Cooling System
The ASI294 Pro has a 2-stage TEC cooling system that enables deep cooling (35°C-40°C below ambient). The cooler requires an external power supply, which is not included with the camera. You may order a suitable power supply from Bintel here.

256MB internal DDR3 memory
The ASI533MC PRO features SONY’s latest back illuminated IMX533 sensor, with a 1-inch square, 9.07MP sensor that is ideal for astronomical photography needs and can be considered as the latest iteration of the venerable ASI183MC Pro.
As you would expect this latest generation camera not only retains key features of the ASI183 series such as an attractive QE figure, high frame rate and along with other excellent characteristics of the ASI183 cameras, but also now includes new and improved features such as zero amp glow, extreme low read out noise (as low as 1.0e), 3.76 microns pixel size and an improved 2 stage TEC cooler giving enhanced cooling capabilities.
1” square sensor
The IMX533 is a 1-inch, 9MP CMOS image sensor in a square format with a 3.76 um pixel size, capable of producing frames at 20 frames/sec in 14bit mode.
Read out noise is as low as 1.0e which makes it comparable to SCMOS or EMCCD sensors and highly suitable for high definition, low noise imaging.
IMX533 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
Low read-out noise, high dynamic range.
ASI533MC Pro – ASI183MC Pro Comparision
ASI183MC Pro
Introducing the ASI183 camera series, the most sensitive cameras in ZWO history. Peak Q.E. of the mono sensor reaches 84%!
▶IMX183CLK-J/CQJ-J
Diagonal 15.86 mm Approx. 20.48M-Effective Pixel Monochrome/Color CMOS Image Sensor
▶High-Speed and High-Picture-Quality Rolling Shutter-Type Back-Illuminated CMOS Image Sensors

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. You can also use ASIAlR to power the cameras. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.
One Camera for All
The STARVIS 2 technology brings ASI585MC Pro more advanced imaging performance compared to other cooled cameras. Its high frame rate makes it not only suitable for DSO photography but also solar/lunar/planetary photography.
Jupiter -Jim Rivera
Moon -Christopher Schementi
NGC3372 ( eta Carina) -Simon Lewis
M42, NGC 1976 (Great Orion Nebula) -Simon Lewis
STARVIS 2
STARVIS 2 was developed by SONY and evolved from STARVIS. It is the latest technology with a wider dynamic range and super-high sensitivity beyond the human eye. Benefiting from it, ASI585MC Pro’s sensitivity and signal-to-noise ratio is greatly improved.
Large Full Well Capacity
The back-illuminated structure improves the camera’s full well capacity. Even with unbinned 2.9μm pixels, ASI585MC Pro has a full well capacity of 40ke-, nearly 3 times that of the last-generation sensor IMX485. A larger full well capacity gets the camera higher efficiency in collecting light, can effectively restrain the highlight area from being overexposed, and also can improve the signal-to-noise ratio.
Zero Amp Glow
ASI585MC Pro exhibits extremely clean dark frames with zero amp glow! No matter how long the exposure and how high the gain value is, you can easily get clean and smooth astro images!
Note: This feature is implemented directly at the hardware level, it does not require software control.
512MB DDR3
ASI585MC Pro uses a USB 3.0 interface, along with the built-in 512MB DDR3 cache, ensuring high-speed, smooth, and stable data transmission.
USB 3.0 Port & USB 2.0 HUB
USB 3.0 Port: Provides 5Gb bandwidth to allow ASI585MC Pro to run at 47fps at 8.29MP full resolution (10bit, high-speed mode).
USB 2.0 HUB: Can be used to connect various kinds of USB devices such as EFW, guide camera, and EAF.
Two-stage TEC Cooling
Thanks to the two-stage TEC cooling, ASI585MC 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 decrease.
Below is the dark current curve of ASI585MC Pro at the temperature from -20℃ to 30℃.
Camera Performance
Low read noise, High dynamic range
The camera has a built-in HCG mode, which can effectively reduce read noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain. When the gain reaches 252, the HCG mode will be automatically turned on and the dynamic range reaches a level close to 11bit. The read noise in this case can be as low as 0.9e. QE (Quantum efficiency)
Based on our testing results, the QE peak value of ASI585MC Pro is 91%. Connection Methods (Back Focus Distance: 55mm)
