About this product

Model:  zwo_asi224mc
Part Number:  ASI224MC

At it’s price the ASI224MC is the BEST colour planetary imaging camera available! 

Peak QE of 75% (better than the ICX618) and no fixed-pattern-noise!  It is this combination of high sensitivity and very, very, low read noise that makes the ASI224MC so special (read noise is the main source of noise in planetary imaging). 

The IMX224 sensor is very sensitive to infrared so can be used for infrared imaging with great success. Sharp lunar images in infrared are also achievable - the infrared image won't have natural colours but after stacking you can convert the image to grayscale for a more natural look. To maximise the sensors IR performance the protective anti-reflection cover-glass does not include UV/IR cut but a seperate UV/IR cut filter can be obtained and fitted for colour imaging. 

Can also be used for solar imaging, though when used with a solar telescope image quality may not be as good as that achieved with a mono sensor. 

The ASI224MC can even be used for Deep-Sky imaging! 

Supports 30FPS at it's maximum 1280X960 resolution and long time exposures up to 1000s.   

Has an ST4 guide-port so can also be used as a guide-camera. 

Supplied with a 150-degree wide lens so you don't even need a telescope to start imaging the stars! 

All ZWO cameras include a 2-year warranty.

Excelente servicio
Friday, 6 May 2022  | 

Como es de esperarse el servicio de FLO es espectacular, tardaron menos de una semana en entregarme la cámara desde UK hasta México, de hecho tardan mas las compras hechas en USA . La cámara llegó en perfecto estado y ya he hecho algunas pruebas con ella, el desempeño es asombroso.

Gracias de nuevo, debo decir que FLO es por mucho la mejor tienda de astronomía!

Saludos desde México.

A really great camera. I’m using it for auto guiding with PHD2. This replaced a earlier ZWO USB2 camera that was unhappy using a USB3 laptop so I upgraded to the 224. Very sensitive it works beautifully always picking up numerous stars. First Light delivered within a couple of days in their usual excellent way. I am one very happy customer!

Great camera

I had this a week ago and took a few videos of the moon to stack, amazing and very simple to use. Can wait for planets to come back in favourable position.
Build quality is very nice and quite lightweight.

Fantastic price/performance planetary camera
Friday, 21 January 2022  | 

I've had this camera for many years and it has aged very well. It has great performance for typical planetary objects (Jupiter, Saturn, Mars). It can also be used as a very good guide camera. Amazingly, the amp glow really is zero; that is highly unusual for CMOS cameras and a feature typically only available in more modern and very expensive cameras (or in older CCD cameras). I have even used this for some spectroscopy experiments. Highly recommended.

ZWO ASI 224MC USB Colour Camera
Friday, 22 October 2021  | 

Owing to the short length of time and bad weather ,I have used it just the once. However first impressions are very good . The driver already installed for my ASI 178, worked instantly and the Full features were present.

Using in the near Infrared does give a different view of Jupiter so I am looking forward to using it on URANUS when weather permits. The Chip is smaller than on the ASI 178 and I found it difficult to locate on my setup ,
but then then is some movement at times on the AZ/Alt type mount. It does look promising
Very Good Service ,as usual from FLO . Brian Banbury

Excellent camera for astrophotography with excellent infrared capability
Friday, 15 October 2021  | 

So glad I managed to get one of these before they sold out. This little gem is perfect for planetary and deep sky astrophotography. So easy to use and has a high frame rate.. As usual great service from FLO and a very competative price.

Brilliant service

So speedy to deliver, and such a brilliant camera. I'm fairly new to astronomy, AP and DSO and my previous two cameras broke. This has been brilliant and look forward to many goo years with it. Thanks FLO.

Have tested during the day. All seems good so far.
Will update more when I can finally use in anger,

Versatile camera

Even though it isn’t new the 224MC has a good reputation for low noise and sensitivity so I gave it a try. Quick delivery from FLO. So far I’ve turned it towards a few DSOs as there are few convenient planets. A great performer that can cope with longer exposures than my 120MC with better results. I’ve made a video with a few images on my Jenham’s Astro YouTube channel.

Very fast delivery, came in under 24 hours! Camera works great, I’ve used it to take detailed close-up pictures of the moons surface and can’t wait to try it out on some planets when the clouds clear off. Cheers FLO!
