Many of you know this already but some may not. I recently got my brand new 12.5" f4.7 Zambuto Optics primary and about the very first thing I did after (while wearing a brand new pair of clean room gloves) installing it along with the Aurora Precision mirror cell into the mirror box with the mirror cover in place and setting them carefully into the scope base was to get out my very bright LED flashlight and give it a good inspection.
Well that mirror looked TERRIBLE, completely covered in dust. Oh, no!
So I laughed and took it out for a session at the dark site. Before the session I gave it a few puffs from the rocket blower just for sport but I didn't bother to train any lights on it again. Boy, that's some fine mirror. My first quartz primary too.
For those who may not yet know, the jokes on me but that's intentional. Nobody should ever inspect a primary with a light. Even a brand spanking new premium mirror will not pass that test.
