Should I polish this fine ground mirror? There is a 3mm pit on it because of an accident but I guess I can live with it. I just want to know whether this pit will do any harm during polishing (scratches, ripple on surface etc). Please do not suggest to regrind with #80 carborundum! I'd rather make it a paperweight It is full thickness (2.5cm thick) 150mm diameter plate glass (6") approx. f/7.5. I was aiming to f/8 but I overshot it a little.
Thank you in advance for your kind replies!
