Using Telescope on K200D?

I have a small telescope (400mm focal length) that I thought could make a nice f/6 telephoto lens. Problem is, I have no idea how to attach it to my K200D. I'm sure many Pentaxians here have done something similar, can anyone tell me what I'd need to get it to work? Thanks and Merry Christmas!

I assume the telescope has a 2" focuser (you'd need that..)

Get an eyepiece to T-mount adapter (this one is for a 1.25" focuser, and would severely vignette, so you want a 2" adapter, which requires that your scope has a 2" focuser)

and a T-mount to PK adapter.

These will get you hooked up to a 1 1/4" focuser.

Just in case your scope has a 2" focuser, then you need something like this to go with the T-mount adapter.

2" focuser is preferable but 1 1/4" will do with out much vignetting IMO.
