I have a ASA 12N I have trouble collimating. The problem seems to be that the mirror can move sideways about 1 mm.
When I moved the OTA from vertical +/- 45 degree a "cluts" sound appeared like something was loose. I removed the back cover and found out that I could move the mirror sideways a bit, like the mirror cell diameter is a bit to large for the mirror size, this movement make my collimation change. Has anyone notised this?
I asume this is not normal, is there something I can do or should I Contact ASA?
I tryed to attached some foam (blue Arrows), se image, to keep the mirror from moving sideways, but that is not a permament solution. I have notised that the 12N OTA have the mirror not glued to the cell.
