One question, regarding your setup at the page you linked. great reading btw.
If you have the setup: Telescope - Barlow - Filterwheel - Camera, and assuming you use the 5x powermate, you should have more then 5x magnification, right? Because the ccd chip is further away then without the filterwheel.
Its the same setup I have in mind, though I need some tubes to move the barow further away, since I got a new focuser and its smaller than the old one so it can not reach the focus point

As an alternative, I could have: Telescope - Filterwheel - Barlow - Camera. This way I would just have 5x magnification, the filterwheel is "long" enough so the Barlow gets into the focus point, but how to I connect the Barlow with the T2 "hole" in the filterwheel? (everything is exactly the same as on your instructionspage).
