Product Description

ASI294MC Pro

asi294Sensor5

20180131_101314_136

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).

▶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.

DDR3

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).

Dark Current

The dark current of the ASI294 is slightly higher than the ASI1600, based on our test results.

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.

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 here.

      just upload one dark frame, please check
      the dark current of 071 is better than 294
      so 071 is more suitable for very long exposure
      you don’t need extra adapter to mount on M48 focuser with 55 back focus

    Hi, I want to buy a new ASI camera for my telecopes, but I’m not sure which color camera is the best for me. I use a C11 with hyperstar and an APO refractor with 900 mm focal length. And I compare the cameras ASI 294/071/1600 currently. I want to use the camera with long exposures till 300 sec. If the full-well capacity is the most important value the ASI 294 would be the best choice. If the dark frames quality is more important, than ASI 071. If the pixel size is relevant the ASI 1600 should be interesting. What would be your proposal?

    with max. 30″ exposure (with a fast hyperstar system)…. is it necessary to have a cooled camera? (my option: ASI294 cool or not cool)




    0



    0
    • Sam Wen

      :

      cool is always useful for exposure longer than some seconds
      the dark current is nearly 10X different
      it’s 0.5e at 25C and 0.05e at -5C, so 30s dark noise is 30*0.5=15e and 1.5e
      so uncooled one is good in winter but not good in summer

      It’s a electronic unit near the pixels, working and heat itself. it emit Infrared ray cause the amp-glow. It can explain all amp-glow behavior.

    Hi there,

    I am interested in lucky imaging due to heavy light pollution and limited time. So far, I am quite happy imaging DSOs with many short exposures of between 10 to 20 seconds and stacking them with the usual dark, flat and bias frames. These are the equipment that I currently use;

    – WO GT71 with 0.8 focal reducer
    – Celestron C6 with 0.63 focal reducer
    – SW AZ-EQ5 mount
    – Olympus OM-D E-M1
    – ASI178MC
    – Astronomik CLS filter (depending on which part of the sky I am imaging)

    May I know which OSC camera will be better suited for lucky imaging and/or short exposure like what I am currently doing, ASI294MC Pro or ASI183MC Pro?

    Thanks in advance.

    Hi Sam
    I just bought the camera and it is on the way from the dealer. However, while I am waiting for it, I read several forums stating that the camera has problems with red and green casts at the edge of the frame due to amp glow since the cold finger can’t cool down the entire sensor. So the camera works better at high gain and very short exposures (less than 2 min). Does it still the same? I am afraid that I could not go deeper into the small faint objects with that type of short exposures. Would you recommend to go to the ASI 1600 MC insted? I already have the mono version that I use exclusively for narrow band and works wonderful. Thank you

      Hi Rodrigo, I reply about it in emails. I quote at here for other customers:
      We have some suggestion about use ASI294MC Pro:
      1. take calibrate frames(dark/bias) in same night after you finished all light frames, same or similar environment temp will keep better consistancy. If take dark in another day, please make sure the environment temp is not too much higher.
      2. Don’t let the cooling power reach 90%-100%, we think about 50%-75% will be a wise choice, which means don’t turn the target temp too low than ambient temp.
      3. Preprocessing in Pixinsight will be a good choice, pixinsight have many useful parameters and algorithm to calibrate and stack the images quite well.
      I think in the post, Andy finally took some great pictures. It’s some tricks in every cameras, I think everybody need some time to know about their camera then use it well.

      ASI1600MC Pro is good for long exposure, the camera have lower read noise at gain=0.

    Hello ZWO

    Any plans (if it is even possible) to improve the cooling on this camera so that darks don’t need to be taken with each imaging session? I have seen a live demo of this camera and it is quite impressive. I am looking at using this camera at doing some lucky style imaging (not EAA) on some large aperture telescopes. My club has an 18 inch Newt and the Museum I volunteer for has a 36 inch RC.

    Hi, what’s the correct backfocus distance when using a C8 with a f6.3 reducer?

    For your camera should be 55mm, but for a C8 with reducer, as far as i know, is recommended to be 105mm.

    Which one should i use?

      :

      We just provide a 55mm reference, the real back focus length depand on the reducer itself. In this case, I think you need add another 50mm extender at the front of imaging train.

    Just double-checking: the optical window of the camera is *NOT* an “IR Cut-off” filter?
    I would like to use this for doing spectroscopy in the near-infrared (700nm – 1000nm) as well as the visible (400nm – 700nm), so the window has to be clear, not a cut-off. Also: by “Operating temperature” you mean the ambient operating temperature, of course? Ie, the sensor can be cooled to -45C (if ambient is -5C) ? -Thanks

      Yes, It not IR-cut filter on the camera, Delta-T is 40degree, your exemple is correct.
