When I view an image, Sirius, The IMAGE in the ZWO is not centered as it is in the Explore Scientific 18/82 eye piece, the ZWO image SharpCap is very high and to the left. If I rotate the ZWO body the image will circle around center from the same distance (like a poorly aligned polar scope). My opinion is the Sensor is not centered in the body of the ZWO. This is a new purchase, should I return it for another or is there an adjustment ?
The second issue is that large translucent circle appear in LONG exposures and if the body of the ZWO is rotated so do these circles so the problem is in the image sensor.
Lastly there seems to be fuzz in the fish eye lens that becomes noticeable while adjusting the gain during setup.
On the plus side setting up the drivers in Windows 7 was easy and when the ZWO worked almost instantly on a Raspberry Pi-3 running AllSky I was super thrilled .
Please Advise , the ZWO was purchased from a major Southern California dealer. Bill P.
