Product Description

ZWO ASI120MM Monochrome 1/3″ CMOS USB2.0 Camera with Autoguider Port

The NEW ZWO ASI120MM is an excellent choice for an affordable planetary and deep sky 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 AUTOGUIDER PORT so you may now use it both for imaging or guiding!

With the ZWO ASI120MM 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, as the old saying says, 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. This monochrome version is recommended for L-RGB or narrow band deep sky photography if you want to get out the best data from your camera and achieve sharp, contrasty deep sky images or planetary images, but if you don’t want the hassle or cannot spend much time and happy to go for a compromise, simply choose the colour version, the ZWO ASI120MC.
With this 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 astro photography…)

Recommended for the Sun, Moon and some deep sky objects

If you have any problem with installing any of the software from the CD, please download them from here:
Firecapture Downloads
SharpCap Downloads

We’d recommend to use the beta version of Firecapture as the 2.2 version is not fully functional with the ZWO ASI cameras…

APPLE MAC USERS:
to use the ASI camera under Mac there are 2 steps to do:
1. install Parrallel virtual machine.
2. flash the ASI firmware.

Here is a link to the update tool for ASI120 (ONLY FOR mac USERS!):

(Please don’t upgrade your firmware if you use a PC.)
Update is very easy, you just need to run the tool on a machine which runs the camera…

See an article in our blog about
How to deal with Newton’s rings in CMOS imaging?

Below is an example of a planetary imaging setup with a Imaging Flip Mirror, ZWO Filter Wheel and ZWO ASI120MM monochrome camera. With the help of a Variable Locking T2 Extension we could achieve parfocality.  The eyepiece holder (that is part of the Imaging Flip Mirror) is also adjustable, so with these two adjastable items we can achieve various positions of the eyepiece thus parfocality can be achieved with eyepieces of various focal lengths. To see approximately the same field, you’d have to use an eyepiece with approximately 6mm focal length. Please note that this setup might not work for a Newtonian telescope due to the long back focus requirement.
