Parfocalising your eyepieces

It is relatively easy to bring a set of eyepieces to the same parfocal standard. Pick the one with the most in travel as your standard and measure how much out travel is required for each of the others.

Ask a lathe owning friend to make up the required spacing cylinders and glue them in place.
