Hi Lee,
i just tried this with my 314L+ and the ED80 and found that without the diagonal in, I needed to put in a Bintel camera projection tube which makes the distance between the camera flange (with the 1.25" nozzle removed") and the 1.25" focuser adaptor to be 70mm.
To focus on a light about 16m away in my dining room, or close enough, the focus draw tube was racked out and the distance between the telescope tube and the camera flange was 180mm.
So, you will need an extension tube of similar length 60-70mm in order to reach focus without a diagonal. I have attached a picture.
Cheers
Chris
