Have double checked this.
In total, I have a total of 14 cm of total back focus which includes my main mirror moving up 1 cm. This is from where my eyepiece focuses to the inserted focuser.
If I add my current imaging train, I still have 2.5cm left (as I can move my main mirror up 1 cm), but I still need to add a filter wheel. But this includes a Lumicon Giant Easy guider which is not ultra thin, my Canon 400d, and my coma corrector.
