The Proteus is a lower-cost version of the ZWO ASI 120MM. It uses the same chip and can be operated using the same driver.
The driver can be downloaded at:

Image acquisition can be carried out using freeware programs. SharpCapture is one good example:

This Proteus camera does not have a 1.25 inch filter thread. If you wish to use 1.25 inch filters, then the following adapter is also required a T-Adapter.
For RGB imaging, the purchase of a filter wheel and a filter set is necessary.
There are numerous freeware programs available for image processing. Autostakkert, Registax and Giotto are all good.
