 I've been using my  Meade DS114  ( 114mm f8 ) reflector telescope and Philips TouCam III for a while now at prime focus which  makes the field of view rather narrow around 10.4 x 13.9 arcmin.  I recently bought a f.6 reducer do  get  a bit wider FOV.  However, when I  attached it to  the camera and place it in the telescope I couldn't  focus the image. 

I determined that  I needed to  get  deeper into the focusing tube. After pondering the problem I decided what  I needed was a bushing that would fit snuggly into the 2" focus tube and allow me to  put the 1.25" camera adapter into it.

So  I ended up  making a bushing out of .75" MDF (Medium Density Fiber board)

If you  need an adaptor and don't feel you  can make one yourself, contact Steve Mogg at WebCaddyHe can probably  make you  one for around $30 plus shipping.

To cut out the bushing I used an adjustable hole saw on my drill press. I first cut the  1.25" hole partially  through so  that  I could use center hole cut by the centering drill as a center point for the outside  ring. I then changed the saw to cut the 2" outside diameter ring completely  through.  To clean out the hole I the middle I again changed it to  the 1.25" size and cleaned it out.
A little sanding finished the job.

This is the holes aw I used
