ZWOptical was founded in China in 2011 by Sam Wen. The company develops CMOS cameras for astronomical applications.

The affordable ASI 120 series of cameras quickly became popular for planetary photography. For some time the company has offered camera systems with cooled sensors, with which you can easily photograph nebulae and galaxies.

The new cameras with the PRO designation, not only have active cooling, but also an improved housing and generous buffer memory. These meet the needs of experienced astrophotographers.
