Subject: ATM eyepiece/camera mount

Hi I am building a 5.5 inch f7 Neutonion mounted on a fork-equitorial

Should I worry about a two inch eyepiece hole, or would 1.25 be enough
  -I'm building a sliding type focuser

I want to be able to do some photography with it, I found a couple of things
used
   
  1)A 'camera adapter' (written on the box) and the actual part only has
'University     Optics' on the side. It looks like its a tube that goes
between the focuser and 
    the camera. It has two screw in 'adapters' with it. One has an outside
thread of       1 3/8 and inside hole of aprox. 1 1/16.  The other has an
outside thread of aprox.
    1 3/16 and an inside hole of aprox 15/16.
   
  2)An eyepiece.  Its undersized, but fits inside the 'Camera Adapter.' It
has 'AH         40mm' on the side.

Could anyone explain to me how these are used? 

Thanks in advance!
