[ATM] Refractor Lens Cell



Hi,

I just polished out my 7.5" achromat and the next stage is a cell to be able to test the lens. Since I made a fraunhofer type lens, do I need to make an adjustable cell or will a simple cell do? From what I've read the fraunhofer does not need an adjustable cell! 

Regards,

Alfredo
