Hi Jay

I reckon you will be fine for visual use. I have a 12" F5 with a 2.14"
diagonal and a low profile helical focuser, my figures worked out the
same or close to yours. You can always trim the draw tube by an inch and
set it up so that focus is obtained fairly close to fully racked in
height. But make sure you have enough for a barlow or whatever other
lenses you use!
