thread etalon lunt50

Post by Ivan »

Hello everyone,

Does anyone know what thread etalon lunt50 has on the side of the focuser? And what kind of lubricant can a pressure tuner be lubricated with?

Thank you

Ivan

Hi Ivan

Which Lunt50 etalon?

The 'red' LS50C is M80x1
The 'white' 50FHa is M90x1

Hi Mark,

I was referring to the internal etalon with a pressure tuner.
