Hi Roel

looks great, but what's inside? A PST etalon ?

It's got to be a PST etalon with a tuning lever added to allow tuning from the outside of the OTA. Probably mounted onto the front SCT threads of the focuser....
Is that correct, Roel?

Fantastic solution! The acrylic cells for the etalon that allow it to sit in the ota are a great idea! :bow:
