Are you trying to replace the objective on an existing Lunt solarscope or trying to mount a Lunt 80mm external etalon to a refractor?

You could use a smaller ERF mounted inside the OTA. As long as the light cone is contained within the diameter of the ERF then that could suffice.

How to find the correct spacing for the Lunt though is another matter. You'll also need a blocking filter
