Refractor Problems...what have I done?

I have an old 6" F8 jaegers refractor. Recently I took the scope apart, had the tube cut down & added an astro physics focuser, flocked & baffled the inside of the tube, & had the lens taken apart & cleaned.
I just put it back together today, and everything looks like it is under water! There is maybe a small area in the center of the field which is almost in focus...but the rest of the field is a mess. I tried reversing the crown...no luck. I don't anything could be that badly out of collimation to cause this. This is really bad! I'm wondering if it couldn't be a spacing problem between the crown and the flint?
Any ideas would really be appreciated. thank you, Bill

Hi Bill --

You need to check out collimation. Might you have shortened the tube too much? With all else the same your focusser will need to be racked out to compensate for the shortening.
It has to be a solvable probem.

Here is a 6" f/8 Fraunhofer achromat. The 6" f/8 refractor seems quite popular, so I thought it might be of some interest.
