Focal Reducer for a Refractor?

focal reducers are avaiable for the better refractors but expensive. You

can make your own... but the issue of in-travel usually means you will
not getthe reduction you hopes for...

How do I reduce the focal length on an ST80 refractor? I have seen
references to modified /reduced focal lengths for refractors on the
captions of some astrophotos. I use a reducer on my SCT. Is there a
refractor equivalent?

Thanks
