Product Description

Diagonal 6.46 mm (Type 1/2.8) Square Pixel Array Color CMOS Image Sensor


Back-Illuminated CMOS image Sensors with Improved Visible Light and Near Infrared Sensitivity that Support 1080p

Sony has developed the approx. 2.13M effective pixel back-illuminated CMOS image sensors IMX290LQR and IMX291LQR with improved sensitivity in the visible-light and near infrared light regions for industrial applications.
A new 2.9 µm-square unit pixel has been developed that combines a back-illuminated structure with technology for improving near infrared sensitivity to further enhance picture quality at low illumination while at the same time realizing Full HD cameras for industrial applications. This realizes two or more times the sensitivity in the visible-light region and three or more times the sensitivity in the near infrared light region than that of the existing Sony product (IMX236LQJ).

  1. :

    Is the ASI290MC or ASI224MC better for planetary imaging?

    • :

      Hi Brad
      The resoultion of 290mc is close to 174, also Max FPS at full resolution is very close to each other, its read noise is close to 224mc.
      So, 290mc is suyitable for planetary imaging, but more suitable for Lunar and Solar imaging.

  2. :

    Hi Sam,

    did you start shipping this comera to customers, if I order today how long will it take to ship? Thanks

    • Sam Wen


      yes, we start shipping now
      but still not enough cameras to ship
      so I think you may need to wait 1 or 2 weeks to get it if you put order now

  3. :

    I want to replace my ASI120MC with new camera, either 290mc or 224mc, is the 290mc a better choice for planetary or is the 224mc?


    • Sam Wen


      I think it’s better if you want to image lunar or solar because it has larger resolution
      otherwise the performance should be very close each other

  4. :

    Why is this not available on AliExpress? And how good is it as an Autoguider? I need to use it for autoguiding as well as planetary imaging. Which one would you recommend 224MC or 290MC?

    • Sam Wen


      we will upload to Aliexpress store once we have it instock
      Aliepxress won’t allow preorder

  5. :


    there are reports that this camera comes with a IR-cut filter built-in, is that true? If so it’s not suitable for IR imaging?

    • Sam Wen


      no, we choose to use AR filter build-in
      so you can still use it for IR imaging

  6. :

    Sam according to this you’ll have used an IR-CUT filter in the first batch of ASI290MC. What about the one’s that you will ship from now on? Are they also from the first batch? Also why is your official dealer not giving the introductory discount? http://www.highpoint…camera-asi290mc

    • Sam Wen


      just asked they to corrected it
      all our ASI290MC produce now use AR protect window

  7. :

    Between the 224 and the 290, would one work better as an auto guide camera? My primary interest is long exposure DSO imaging but if I’m going to buy a guide camera I would like to get one that can also work for lunar and/or planetary imaging, but my primary concerns is how well it would work for guiding as opposed to if it’s better suited for lunar or planetary…

    • Sam Wen


      maybe bigger pixel size allow you to easy find a guider star
      but mono camera is far sensitive than color one
      so maybe ASI290MM is your choice

  8. :

    As an ST4 guide port is built in, can the cooled version of these cameras “self guide” if used for long exposures?

    • Sam Wen


      no, they are not self guide camera
      the ST4 port allow you to control it through your PC

  9. :

    Hello, what is the present delivery time for a 290 color?

    • Sam Wen


      I think we will have enough in next week

  10. :

    Sam, I’ve just taken delivery of the 290mc and still experimenting. Apart from putting on my scope I thought I would give it a go using a Geoptik mount which allows Canon EOS lenses to be used – thinking that the combo may be ok for some DSO when tracked. Problem is I can’t get focus with the standard coupling of the 290 to the mount. A bit more experimenting shows I will need a t-mount extension tube, but not sure which one to go for. Any suggestion as to what length tube to get? Thanks

    • Sam Wen


      which Canon-T2 adatper did you use?
      our Canon-t2 adatper is adjustable and suitable for all ASI cameras

  11. :

    Sorry Sam, I don’t think I explained the setup properly. The Geoptik mount is an adaptor which lets you screw a Canon lens into the front and the other side has a standard t-thread which allows the camera to be screwed in directly. The adaptor can then be mounted on a tracker or piggy backed on a telescope. If the 290 sensor isn’t in the same plane as the Canon sensor would be, you are unlikely to achieve focus. Since my previous email I have discovered a 10 to 13mm t-extension tube between the adaptor and camera gives me a focus at least for a Canon 50mm lens. I’ll let you know how it works out.

    • Sam Wen


      got it, the back focus of 290 is 12.5mm
      the back focus of cannon lens is 44mm
      so some caculation needed

  12. :


    Would the ASI290MC be suitable for video astronomy or do you have another camera that would be a better fit?


    • Sam Wen


      actually, all our cameras suitable for video astronomy

  13. :

    I have received the ASI290MC camera, nice little device. However, tracking through ST4 is not working. I have installed all drivers from your site, but my mount will not move in PHD Guiding. What can I do?

    • Sam Wen


      Hi Paul
      you can use a multimeter to measure the ST4 port
      to check if the direction pin connected to pin 2 when you click the direction

  14. :

    Hi Sam,

    I don’t measure any voltage change on any of the pins when trying to steer from the software. I’m assuming it’s a driver issue.
    For now I’ve ordered your ST4USB converter to see if that will work.

    • Sam Wen


      there is no voltage change, just the direction pin is connected to the common pin(pin 2) when you guiding

  15. :

    Hi Sam,

    Quick update; the USB ST4 adapter came in today, it doesn’t work either. When plugging into the computer no new entries show in the ‘device manager’. I tested it on different machines, on windows 7, 8.1 and 10.

    What now?

    • Sam Wen


      USBST4 don’t need driver, it show as HID device just like keyboard or mouse
      you can use our ASCOM driver to connect USBST4 and control it

  16. :

    Hi Sam, I am looking for a camera for Lunar and planet photography (for a start). Maybe sun later and sometimes DSO. can you explain what criteria are making a camera suitable for which imaging (planetary, moon, sun, DSO).
    Is it the frame rate, the resolution, the pixel or sensor size ?
    Difficult to choose between 290 MC and 224 MC.

    • Sam Wen


      I think DSO imaging need big sensor size
      290’s high resolution is more suitable for Lunar and sun imaging than 224

  17. :

    hello – what software should I use for autoguiding with an AS290MC ?

    • Sam Wen


      you can use PHD2

  18. :

    Hi Sam, want to use my new 290 MC for microscopy sometimes. Installed uManager and the Micromanager plug-in available in the download section. But uManager does not see the 290 MC. How can i check if the plug in is installed properly?

    • Sam Wen


      please email our technical supporter: Yang.Zhou(at)
      he may reply a little later as we are having vacation now

  19. :

    Hi, If I order ASI290MC, in next day or 2, how many does it take to ship to Chicago, USA address? Thanks.

  20. :

    Hi, If I order ASI290MC, in next day or 2, how many days does it take to ship and reach to Chicago, USA address? Thanks.

  21. :

    se compro la ASI 290MC color nella confezione è previsto anche l’obiettivo da 2.1 mm?

  22. :

    Is 2.5 mm all-sky wide-angle lens included ? I’m slightly worry becouse in description is only body of camera. Thanks

    • Sam Wen


      no, this is 4/3″ format camera, 2.5mm won’t work
      you need 6 or 8mm all sky lens suitable for M43 cameras

  23. :

    I have used your cameras straight out of the box for all sky, lunar and solar imaging and guiding, but I am still in the dark about getting higher fps. How do I use the different bit settings? 10/12 and so on. How do I find them and how do I change them?

    • Sean Wang


      Hi David
      There is some way to get faster FPS.
      1. turn High speed mode on
      2. turn USB bandwith(usb traffic) to 100%
      3. use SSD to record(HardDisk is too slow)
      4. exposure must be short, if you use 1/10s exposure, that means you only can reach 10fps.
      5. use USB3.0 port on your computer.
