Bought the new Explore Scientific reducer/field flattener.
See it here:

They say it is for f7 - f8 scopes.
It is 3", but they have an 2" nosepiece adapter available as well.
It works fine with my Explore Scientific 127mm APO. It will also work with the Explore Scientific 152mm APO.
I am testing it with other scopes, stay tuned.
