Hi all. I’m making my first mirror. I seem to be stuck on the polishing and hoping to get some advice. The polishing preceded great for around the first four hours with the surface quality improving at a steady pace. After that point and another 5 hours polishing there has been no noticeable change at all when testing with a low powered red laser. I’m still getting a surface reflection which looks like tiny barely see able pits not touching each other but close together. Sorry that’s the best description I can think of and it’s too small for a photo. Anyway the mirror is six inch. Glass is suprax. The last grit I used for fine grinding was 1600 not sure what it was actually made from the seller never said. White cerium oxide for polishing mixed with water to a milk like consistency. I’m also unsure of what kind the pitch is but to my unexperienced eye it seems to be fairly soft. I’m certain, but could be wrong, I finished of the fine grinding correctly. Maybe I have just not polished for long enough? I have run out of the cerium oxide supplied with the blank which was meant be enough to finish the mirror. I live in an isolated area and have no one to ask for some hands on help and would appreciate any advice or thoughts. Also I'm in Goughs Bay Vic if there are any other amateur telescope makers in the area it would great to here from you.Thanks Jason
