Is it permitted to ask how to stack a Coronado PST external etalon on a Lunt 60?

You will need an adapter. Call LUNT , they will make you one.

You can adapt almost any filter with the correct adpt. ring. Years ago I had an adaptor made to use my 40mm filter to my 60mm Solarmax filter. It works but it gave a much dimmer and smaller sweet spot. I now connect the 60mm Solarmax filter to my Lunt 50mm filter.
