Thread size & pitch
For the 60mm T-II Coronado rich-field Etalon. I'm trying to see if they will mate up to the TV Pronto or a TV 76 cap threads ?Also are the thread sizes "universal" ( to Coronado)
On the type 2' & 3's on the RF Etalons.
I know there's the adapters for Double stacking made by Coronado, are the adapter threads the same
Any info. Would by very cool & welcomed
