As I was removing my secondary to install a dew heater on the back, I noticed a very small scratch in the mirror. It's about 3/4 of the way down and toward the middle. It's very small, maybe 3-5mm. I initially thought it was an eyelash/eyebrow follicle.
The mirror is a 3.10" minor axis 1/30 wave secondary from Antares mated to a 16" f/4 quartz Zambuto primary mirror.
Any cause for serious concern? Would hate to have to replace it as it's only a few months old.
I'd appreciate your thoughts.
