sure you can use them to take images and if you cool the chip its actually a pretty capable camera for DSO's i was just saying its not ideal for planetary work because of the progressive shutter/pixel size. because of the chip size though its great for lunar work. also the Orion guider is just a re-branded QHY5/Qguider
heres some planetary/lunar shots with one:

heres a deep sky shot with the cooled version (you wont get anything like this with any of the standard guider cams but it illustrates how much cooling helps)
