The making of 26 inch DK telescope -8, redo polishing

文章 Chanlunlun » 週四 10 4月, 2014 11:08

Dear ATMers,

The second round polishing has been started. This time we are polishing by machine.

The polishing machine is actually an item left behind from our previous 30 incher project. Instead of throwing the machine away we dismantled it and kept it inside the store room hoping that someday it would be found useful again.

Now we are using the machine again. Only this time it handles a smaller mirror.

Best regards
Chan Yuk Lun

Polishing in action, very little human power is required.
