Barry, at this time I an not even looking at my main camera I am pretending it is not there. No mater how far in or out I focus I can getting nothing visible through the guide camera it as if it is not picking up enough light.
Yes the flat edge of the prism is towards to telescope and I have adjusted the prism all the way up and down (down collects more light and still nothing).
This one seems to have me stumped
