Hi
Really basic question much to my embarrassment.
I'm using a QHY-8 (not the round one, the square one) and a field flattener with a william optics GT-81. The camera requires about 55mm of back focus after the field flattener.
I know that I need to use spacers to do this, no problems, but have no idea what the difference between all the threads are. I have purchased a set of T-spacers but after looking at them when I un-boxed them, they look a little too small to fit on the QHY8. Other threads I've read say things like they use a T-2 to 2" nose piece, some say things about 48mm * 0.75 thread. GAH!
I am lost in the mire of thread differences and have no idea what the thread on the QHY-8. Before I attempt to use the force (
), does anyone know something that can shed light?
