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.

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!

Haven’t had a chance to use this with the telescope as yet. But I have set it all up the my laptop and I’m already impressed with it. Can’t wait to use it now. Flo sent it out so fast, and gave me loads of help and advice when choosing this product. Will definitely be back to buy again.

Total novice in Astro photography so with a lot of help and advice from the lads at First Light Optics I chose this camera to have a play. I followed the ZWO instructions to download the driver first, then plugged the camera into my laptop and it all connected up. As this camera has a fisheye lens attached, it showed images straightaway, no problem. I have not tried it outside yet, but I am confident that I will get some recordings to try in the ZWO ASIstudio software to start with and learn about photo stacking etc.
So far so good, many thanks to FLO for all the help.

I've been making my mind up about one of these for planetary imaging for a while. The product arrived promptly, in good condition and I'm looking forward to giving it some good use. Thanks FLO!

This is a very good and cheap color camera. I have used it for deep sky and solar imaging so far and I am very satisfied with the results.

I have been very impressed with this planetary camera by ZWO. Once you become familiar with the software Sharpcap the 224mc camera shows how versatile it can be. So far I have taken images of Venus and the Moon and M42. I am looking forward to using it this July when Jupiter, Saturn and Mars are in opposition.
ZWO ASI 224MC USB 3.0 Colour Camera Wednesday, 12 June 2019 | Khalefa
I really like this camera, it is very sensitive and low noise, using USB3 port allows this camera to reach a very high frame rate which is very important when imaging.
Easy to use after installing the driver, highly recommended indeed!

Hugely sensitive, really fast frame rates under USB3.0, IR sensitivity on all pixels longer than 810nm - this is a lovely camera.
The read noise being low and sensitivity being high means short exposure stacking for DSOs works fairly well - and allows lucky imaging techniques to bring out *detail* that would not normally be there.
I haven't had much chance to use this as a planetary camera yet but all indications are that this will be epic for that purpose, with a tracking mount and the use of ROI in the capture program, should mean lots and lots of sharper frames to stack.
I've got a second one of these being set up as an all-sky camera, using the sensitivity and resolution to get decent videos.
Overall I'm *really* happy with this camera.
