On the AM5 product page, it says they don't recommend using telescopes with focal lengths longer than 900mm, but in their marketing photos, they have a Celestron C11, which has a 2200mm FL. I have an 8" EdgeHD and unless I'm using my Hyperstar V4 @ f/1.9 390mm FL, my f/7 focal reducer only shortens the FL to around 1470mm.
Thus, is the Am5 only for small scopes like a Red Cat or maybe a C6?
