Make sure your scope is perfectly collinated or try it on someone elses
scope to see if its repeatable. If you have a f /6.3 this is normal on
this scope but on a f /10 it should be in focus. I noticed the same
problem with my f 6.3 and my TV 40mm wide angle. The Paracorr is
designed for the newtonian.
