The making of 26 inch DK telescope -3, #1200 done.

文章 Chanlunlun » 週五 13 9月, 2013 20:02

Dear ATMers,

Today we finished the #1200 grits. It means that all grinding stages of the mirror has been finished. Polishing will come next.

However before commencing polishing a series of preparation has to be done. These include making the mirror stand, Foucalt tester, tester stand……etc etc - small jobs but quite time consuming.

We will try to keep the project proceeding with appropriate pace.

Best regards
Chan Yuk Lun

After the #1200 grit, the surface of the mirror is very smooth, so smooth that it reflects at gracing angle.
