Margo,
You have the Crayford Focuser. These are the parts below. (thanks to Geoff for assistance)
If your tension adjustment is too loose your eye will push the EP out of focus. Too tight and it becomes hard to turn the focus knob. Find a spot where you are happy with the movement.
Your scope should not move changing EP's. Which way is it moving? Up & down or Sideways?
