ASI120MM-S or ASI120MM ?

Other than the USB3 interface, what is the difference between the ASI120MM-S and ASI120MM?

If one is only using USB2, is there any reason to get the ASI120MM-S rather than the ASI120MM? The camera will be used as a guider.

Thanks!

Don

1.ASI120MM-S is faster than ASI120MM 60FPS VS 30FPS

2.ASI120MM-S is more stable and suppot more OS such like linux Mac_OS

so no doubt choose the ASI120MM-S

Thanks for the reply Sam!
