Hi mate. I've got the PLB-Cx version, without the peltier, but can be added as a kit at a later date. its a nice little camera using the same sensor as a ASI120MC Color USB2.0 Camera.1280 x 960 and you would get similar results. you can buy them with or without the peltier cooler which can be controlled through the software Being a new camera the software for them is being updated weekly, the software is getting better with new features and bugs ironed out, matter of fact a new beta as been released today. Yes it can stack on the fly, darks, focus and guiding, exposure infinity but you expect a lots of hot pixels which is the norm with type of sensor and with the peltier it will reduce it a lot. I've not had chance to give it a work out yet on DSO's . this will give you a idea of the size of it with a usb dongle propped up against it.
