So if you measure from the lens 816mm with a tape that is the distance it should reach focus. So this is the distance to the eyepiece lens.

Thank you Darren, I'll get my tape out and measure it. When you say the lense of the eyepiece, I'm assuming that's the first lense at the bottom of the eyepiece yeah ?
