I have a 290mm mini and a few 120mm mini guide cameras, and now a 220mm mini. This is definitely an upgrade from the 120mm mini and definitely on par with the 290mm mini. I would have preferred smaller pixels but the much larger field of view and available higher gain capabilities is worth the upgrade. The noise is super low and so far it has not disappointed. It also comes with a much better usb-c cable than previous models did. I am pairing it with my 644mm scope and it is working great without any issues. Good clean images even at higher gains!
