I had the camera bolted directly to the EFW7 which was the recommended way, Agena, Zwo and you tubes. Taking darks then becomes a problem(leaks) unless you take the camera off and put the front plate back on and the screw cap. So I did that and shot darks and most(not all) have white band across the long edge on top as in the photo I attached. Would be great if ZWO included proper adapters in the EFW kit or camera to be able to not bolt directly. I know some people are doing that and might find the adapter(s) for that elsewhere. So we have to make a dark library of various exposures to last 6 months and bolt it back? Doesn’t seem optimal.
