Product Description

ASI094 logoBigger than bigger

The ASI094MC Pro camera integrates the Sony IMX094 full-frame sensor (36 mm x 24 mm). It is ZWO’s first full-frame cooled camera, has 7376 x 4928 pixels, and supports BIN2, BIN3, BIN4 mode. The pixel size is 4.88 μm x 4.88 μm.  This camera provides 14bit ADC and its full well is 52000e.



DDR Memory Buffer

The ASI094 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.

Astrophotography Performance

ASI094 Pro offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak 56% and much more.



IMX094 vs. KAI-11002

Compared to old fill frame CCD sensors such as the KAI-11002, the IMX094 has higher resolution, higher QE with lower read noise and faster FPS.

Unique Tilt Adapter

ASI094 Pro includes unique tilt adapter. Say goodbye to tilt problems forever !ASI094-tilt-adapter-3mm

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: can provide 5Gb bandwidth to let ASI094 Pro run at  5 fps at full resolution(36Mega).

ASI094 Pro camera has one full frame sensor, so the power consumption (650mA@5V) is much higher than other cameras. But USB3.0 can provide 1000mA current, so ASI094 Pro can run standalone under USB3.0 host, it doesn’t need external power supply.

You need to connect the external 12v power supply if you connect the camera to USB 2.0 host which can only provide 500ma current.

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.

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can manage your cable better with USB2.0 hub. There are 2 short 0.5m USB2.0 cable come with ASI094 Pro. the power of hub source from external power supply if you connect it.


Cooling and Anti-Dew Heater

ASI094 Pro has a two-stage TEC cooling system that allows deep cooling (30°C-35°C below ambient). You will need an external power supply to power the cooler. An AC-DC power adapter is not included in this package, however you can order one from here.

The anti-dew heater will heat the AR protect window to avoid any dew problems. The heat anti-dew heater power is around 3.6W and can be turn off  in software to save power.

  1. :

    What does limited edition mean? Only a few pieces available forever?

    • Sean Wang


      Yes, we don’t have much of them for selling.

  2. :

    Will a color calibration tool such as Spyder Checkr be useable for correct color calibration of the OSC? If so, this would be better than using simple visual estimation of color balance. I have not used this before so just wondering if it may be helpful.

  3. :

    chancy, I have the Datacolor Spyder 5 and I would not be without calibrated computer screens for my final manual verification. However, you should color calibrate during post processing and you will have to learn techniques/methods like G2V (white star) calibration. I stick to the latter whenever I can, but it looks to me that most images you see on astrobin and around, are simply color adjusted to be “pleasing” (at best).

  4. :

    I see that the camera “can be ready at Oct.”, which I guess mean it will likely be shipping before the end of the year.
    I guess that my PayPal account will be completely charged at the time of order?

    • Sam Wen


      we are shipping now

  5. :

    How is its amp glow? Could you provide dark flame data?
    Is the actual sensitivity of IMX128 higher than that of IMX094?

    • Sam Wen


      there is nearly no amp-glow
      the sensitivity of 128 and 094 is very close to each other

  6. :

    How do i do a color calibrated profile for the fits file? I use a commercial color checker and it has a profile for camera RAW files so that colors are accurate, but I am not sure how to apply this to the FITS that this camera produces. Please advise,thanks!

    • Sam Wen


      do you mean color bayer pattern? it’s RGGB

  7. :

    When binning, does this camera retain color information?

    • Sean Wang


      Yes, It does.

  8. :

    1. I need more informatiion for hardware binning.
    – pixel resolution after binning

    2. Where can I get the SDK and SDK manual for linux of this camera?

  9. :

    When will this camera be available for shipping?

    • Sean Wang


      Sorry, it is not available this month. When it is available, we will update the status of 094.

  10. :

    Sam, what size filters should be used with this camera and sensor? 48mm/2″ mounted or 50mm unmounted?

    • Sean Wang


      2″ or 50mm unmounted will be suitable. we provide a M54-M48 adapter in the box. You may put 2″ filter on that adapter. For 50mm unmounted filter, only way is put it in a Filter wheel.

  11. :

    Can I use Canon Full frame lenses without any vignetting on this sensor? Which adapter do you recommend? and still use 2″ filters?

  12. :

    Interested in this camera, I saw it was on sale somewhere where is the sale version? Also does it have Nikon Mount to add F mount lenses?

    • Sean Wang


      Hi John. sale was in last year. We made a M54 Nikon adapter for DSLR lens.

  13. :

    Thanks for the answer, also which filter do you recommend and how do you use them when you mount Nikon lenses using M54 adapter?

    • Sean Wang


      We don’t have suitable filter, 2″ filter still not big enough.
