Received my c mount adaptor and it now holds my Nikon 18-55 lens (I also have a 55-300). Hoping to try it tonight as hand held. Will have to wait for another day to make primary mirror adj on the dob and try as prime focus (early shift tomorrow). I also bought the eye shade, dimist lens and sacrificial window (made a minor mod to fit with gain control and a safety strap. I continue to thank you all for the guidance.
Now I am thinking of calling Astronomics and placing an order for the AT F/7 115 ED triplet refractor and an Ioptron IEQ30 mount. I suspect this would be a good match for this NV equipment and standard viewing or SC "live view" not to mention as a better g&g setup.
