I've been all around town trying to find the right grit. Knowing that some of you recommended carbodorum grit 600, I went to a jeweler who just happen to be an amateur of astronomy who built and polish his own lens. So he sent me to a few astronomy shop where you buy telescope and they all seem to have this in stock or at least know about this, unfortunately they did'nt have any carbodorum at the time.....but that's another source for sure.
The only thing I found for now is aluminum oxide but someone told me that this is not rated the same way, anyway I bought a small quantity of each grade they had in stock 80 240 & 400 but I don't know if this would do....so I ask for help before ruining another glass! Some people told me that it's easier to work with carbodorum because it stay on the glass longer....but another one told me that it's a lot coarsier than aluminum and gives a less uniform finish.......any comment would be appreciated.
