I am having trouble imaging through the Barlow on my Q 3.5. Using a ZWO camera on the axial port I have no trouble imaging the moon and Jupiter etc. But I would like to be able to Image through the eyepiece port and put in the Barlow. If I put the camera in the I eyepiece port t I can again image Jupiter (for instance) but once I swing the Barlow into place the image goes away. Not even light for an out-of-focus image can be seen. My camera has a 23 mm diagonal so it should be plenty big to capture the light coming through the Barlow even if the image is a bit off-center. Any help you can give me would be appreciated.
