Hi all,

I recently made the jump to AP and I've hit a small problem achieving focus.

My set up is Megrez 90 > WO pflat4 feild flattener > T ring > canon 550d

My problem is that when i wind the focuser all the way in I am still not quite in focus.

Anyone know why I can't achieve focus? I'm not sure if it's the flattener (WO states that it works well with the Megrez 90) or if I just need an extender or reducer or something.

I should also mention that i can happily achieve focus with a diagonal and eyepiece.

Any help would be great, thanks!
