Trivial. The SCT should have an eyepiece adapter, hopefully 2 inch. This piece goes in at the plain end, and takes the camera at the threaded end.
They also make them for 1.25, that will likely vignette.
Not trivial at all. Getting that very inexpensive mount and an 8 inch SCT to track astrophotography targets well for doing astrophotography. Might work for EAA, but won't for traditional imaging. Classic example of the "too big a scope on an inadequate mount" beginner mistake. Seen over and over and over... Extremely common result:
"I regret spending the first 6 months trying to learn imaging with an 8" Edge, with that scope it was a losing effort. Fortunately got a nice little refractor, and not only have the quality of my images improved but I'm actually enjoying the process of learning how to do it!"
That was traditional imaging. EAA could maybe work.
