Where the eyepiece is in the last picture. Almost too much back focal length without a classic focuser. If I fail at getting the secondary focuser working well, then I can always fall back onto using some sort of Crayford type. I would hate to do that, because of all the potential alignment problems. Just because a Crayford type focuser works well, it does not mean that it has no co-axiality/co-linearity and orthogonality problems. Those are difficult errors to deal with in a Crayford..
