Both the primary and secondary mirrors show obvious signs of age. They were both coated in silver when Ron got them, but they were starting to show through and the silver was getting thin.

Ron got them both aluminised a while ago so they are working beautifully. The primary is very thick and over 9 inches in diameter.

I had them set up on a timber jig last month and took a first light afocal of a hill about 7km away. The grass stalks on the side of that hill were clearly visible. Later that night I got a good shot of the moon.
