Hi Brain,
I got a 9.25HD. I presume you have read the manual (sorry for asking).
The photo looks OK (nice scope
), with the diagonal. Make sure you have 'completely' backed off the locking screws, which are the other two screws on the back of the scope. If not they will prevent the primary mirror from moving back and forth and bring the image in focus.
I can get focus with the 23mm EP, incl. the diagonal so it is possible (just so you know).
cheers,
Bram
