Product Description

ASI294MC Pro

asi294Sensor5294pro logo

The ASI294MC Pro is the first camera in the world equipped with the latest Sony sensor IMX294CJK. This is one of the top-selling cameras from ZWO. Looking at the specifications and comparing it to the relatively low price, it is easy to see why. Some of the highlights include:

  • back-illuminated sensor – improving sensitivity and reducing noise
  • 4/3” format with 4.63 um pixel size – ideal for many types of telescopes
  • 14-bit ADC– giving high dynamic range of 13 stops
  • An impressive 7ke- full well capacity- helping to reduce the issue of, for example, saturated stars.

On top of this, it also has a very high QE-value with a peak of over 75%. If you are looking for a small-format OSC camera for astrophotography, you can’t go wrong with the ASI294MC Pro.

294MC Pro3

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 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 SNR1s: 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

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

 

14bit ADC w/ 13 stops DR

The ASI294MC Pro has a 14bit ADC unit, allowing it to achieve 13 stops of dynamic range. This is an excellent characteristic for deep sky imaging, which inherently needs high dynamic range. At 13 stops, the ASI294MC 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.

294 Gain RN DR FW vs gainFull well Capacity

The ASI294MC provides a great full well capacity of 63700e-, which is 3 times higher than the capacity of the highly regarded ASI1600. Even bright stars won’t saturate under long exposures. This also means that this camera can achieve higher SNR (signal to noise ratio) with just one single exposure.

 

Reliable Mechanics

ASI294MC Pro has the 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 well 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). 294QE

Dark Current

The dark current of the ASI294 is a bit lower than the ASI1600 at same temperature, 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. ASI294MC Pro Dark Frame

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 (12bit, high speed mode)  at full resolution(11.7Mega).

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

Thanks to the two-stage TEC cooling, ASI294MC Pro can lower the CMOS sensor temperature to 35-40 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.

*The Delta T 35-40℃ 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. 
Please notice that the camera needs to be connected to an external 11-15v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-15V to power the camera. If you don’t have one, please click here to buy a 12V power adapter. There are 4 different standards  for different countries, please make sure you selected the correct adapter when placing the order.

Q & A: 

1. I noticed amp glow present on the corners of my dark frames,  how should I remove it?

Please don’t worry about that. The amp glow is pretty normal actually. You may learn “What is Amp glow and how do I manage it?” here: https://astronomy-imaging-camera.com/faq

2.  I’ve heard there might be strange patterns on some ASI294MC Pro stretched images, does this mean the camera is defective?

NO, it is not a defect, and it is just a characteristic of the sensor. The pattern calibrates out of the light image with proper flat frames. A proper flat frame is a capture using an evenly illuminated light source, dimmed down to achieve an average ADU value of 24,000 (this is up to the user and their setup – recommended the histogram peak at 1/3 to 1/2 from the left, as shown in the figure below), a 5-second exposure, captured with the same gain and focus point as the light frames.

Please notice that the camera needs to be connected to an external DC 12V @3A~5A power supply adapter for use (connector 5.5*2.1mm, center pole positive). If you don’t have one, click here to buy a 12V power adapter. There are 4 different standards for different countries, make sure you selected the correct adapter when placing the order.
Or you can also use lithium battery with 11-15V to power the camera.
Just be aware that power supplies out of this range might cause irreversible damages to your camera.

    Hi,
    in Ascom driver settiing when i use the unity gain mode, as default, the offset value is 30. Is It right?
    The same value is shown also for HDR mode. Is this right?
    Does exist, for ASI 294MC Pro, a graphic with gain versus offset?
    Many thanks

    Hi,
    I’m enjoying the ASI294MC Pro – though it can be a bit tricky to calibrate with flat fields. What are your suggested settings for use with SharpCap 3.2 when saving to FITS (not using ASCAP)? Second question: I tried joining your BBS over a month ago to ask this but never received the confirmation email, so: last December a user asked if ZWO is considering developing a camera around the IMX492, as the monochrome version seems very much like a monochrome version of the IMX294 in the ASI294. Since I can’t ask at the ZWO BBS forum (yet), I would like to reinforce this request: is ZWO considering developing a camera around the (monochrome version of) the IMX492? Thank-you.

      The ASI294MC is a color camera, which is different with ASI1600MM(monochrome). Which camera you want to choose depends on whether you want to take monochrome photos or color photos.

    I have just purchased a 294 MC pro which I am very grateful for but I have a question about it. I have been using the software with it and have been cooling the camera down to -10, but I wondered if it would be a good idea to make a note of the temperature outside, say 5C, before cooling it down so that before I switch the camera off I can tell the camera to go back to that 5C temperature, rather than just switching it off, because that could cause a thermal shock. Is that a good idea… Thanks 🙂

    Hi. I’m relatively new to astrophotography and am using an ASI178MC on a 750FL / 150 aperture scope (F/5). I am trying to capture DSOs but the field of view is too small. I bought a 0.5x reducer but will have to deal with back focus issues. I was thinking of getting this ASI294MC Pro camera to upgrade my 178. Will this camera be able to fit large DSOs such as Orion and Rosette Nebulas without the need for reducers?
