Product Description

ASI294MC Pro

asi294Sensor5294pro logo

The ASI294 is the first camera in the world equipped with the latest Sony sensor IMX294CJK.

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). i_imx294

▶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 buffer

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.

294 Gain RN DR FW vs gainFull well Capacity

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. ASI294_600X600NEW

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 294 DarkCurrent VS T

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

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 here.

Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 11-15V.

Using a battery 11-15V is also suitable for the cooler power supply.

      You can refer to the “Specification” in this website, the camera power consumption is 650mA at 5V, and the cooler power consumption is 12V at 3A Max.
      We do not suggest you use this high voltage battery.

    Hello
    I read on Cloudy Nighst that there should be an Asi294mm pro.
    Is that right ???
    Is this a modified imx294 sensor or is it a monochrome sensor?

    I would like to use this ASI294 pro cooled with 1.25″ filters and the manual 5-filter ZWO filter wheel. Will I need any optional accessories to reach 55mm backfocus?
    Furthermore please advise if this is currently in stock as of 15 Aug 2020.

    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.

    I would like to ask if this camera will be suitable for telescopes with focal length 1250mm F5 for DSO or the ASI1600MM will be the better option?Budget and post processing are not the issues.

      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.

    Hello. I have a 224mc for guiding and a 294mc pro for photo. I use Prism software for capturing and dealing with all my accessories. What is the best way to connect the 2 camera for guiding ? The 224mc pluged into the back of the 294mc pro ? Or the 2 cameras plugged itself in the usb hub ?

    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?
