The NEW ZWO ASI120MC is an excellent choice for an affordable planetary camera or deep sky one shot colour camera for those who has just started in astro photography, but cannot spend a fortune on a specialist astro photography camera or want to replace a modified webcam or a cheaper planetary imager. This NEW version also comes with an ST4 AUTOGUIDER PORT so you may now use it both for imaging or guiding!

With the ZWO ASI120MC camera you can achieve better results than with those beginner cameras. We are not saying that anything is wrong with those cameras like the TSSI or Scopiumcam, but this is just simply better for a still affordable price.
If you however want the ultimate camera, go for a Moravian Instruments camera that you may also find on our website, but of course for more bucks.
Basically, according to the old saying, you get what you pay for...

According to customer feedback, these cameras worth every penny invested.
Mostly used for planetary imaging, it can also be used for deep sky imaging up to a certain level or even as a guide camera. With the ZWO ASI120MC you won't have to spend lots of time to get beautiful images, however, if you want to get the best results from this range of cameras and you have plenty of time to spare, why not to try L-RGB or narrow band photography with the monochrome version of this camera, the ZWO ASI120MM. (If you go for the monochrome version, you'll also need a filter wheel and a set of L-RGB filters or H-alpha and OIII filters, and maybe even H-beta and SII filters as well for narrow band photography...)

Total data used is about one hour to create the animation.  It's been created in Winjupos.
