Once it is done, you can just leave it in that spot for the rest of the
session- OR-
Determine where the best focus spot is and put a sleeve of the correct width
around the barrel of your eyepiece. A piece from one of your eyepiece
endcaps will work perfectly. To make all of your eyepieces parfocal with
each other see Sky and Tel Jan/96 pg. 86.
