The USB3.0 version ZWO ASI120MC/MM-S 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 version comes with USB3.0 connection that gives you the opportunity to use it with newer laptops at higher frame rates, thus achieve even better results in planetary imaging. It comes with an AUTOGUIDER PORT just as its previous USB2.0 version, so you may use it for both imaging or guiding!

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-S USB3.0 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-S USB3.0. (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...)
