Issue with Lunt LS60THa Pressure Tune
Issue with Lunt LS60THa Pressure Tune
Hi, I notice my lunt 60THa pressure tune cannot get focus to sharp image. I can get image but it is always has issue of sharpness. The edge of the sun appears to have some dim shell above it. When compare to another lunt 60THa, there is different in sharpness. Is it possible issue with collimation of etalon or focuser?
