Yeah infocus issue...because they added a ring to the image focusing train when adding a new focuser...which put the whole train back 25mm or so.
Anyway I put on a ML 2.5" CFL with motor. of course you might not want the motor and this save somewhat. I chose the ML because I had TV 2.4" camera adaptors and other stuff that fits the ML very well.
Since mine is 4.5" travel then I can easily reach focus in and out.
If your imaging they usually sell the 3" travel DT and you can screw on adaptors directly. If for visual then the 4.5" travel DT is usually used.
But that said...if your thinking of the ES 0.7X reducer flattener (for imaging) then this is a 3" unit...your going to need a bigger TD...or a 2.5" to 3" adaptor. I don't think ML make such an adaptor thus you have to use the ES 2" adaptors. Kinda defeating the purpose isn't it.
I'm sure Ron can make a 3"...you have to ask
Basically think about what your going to do with the scope...visual/imaging or a mix as this effects what you need in focuser.
