Now that I have a working powered German EQ mount I am ready to do the deed with prime focus. I've been told that I need to move the mirror up the tube and need some guidance.
I have an 8" newtonian and I think an f8 at 1200mm or 48". I have all of the connections for my two dslr's.
Any idea how far up I need to move the mirror assembly? Thanks.
