I want to take photos using the extra tube on my microscope. I bought an adapter and hooked it to the camera and it slid into the microscope with ease. I can see the image on the screen when I use real time, but I can't get the camera set up to take a picture. Auto doesn't work because there is "no lens in the camera." I've tried several random settings and some of them allow the camera to fire with very slow shutter speed but nothing appears in the photo que. I am clueless and would love some advice. The adapter is from Amscope and has 2x on it.
