I’m going to be building a 12.5″ Dobsonian telescope. For the primary mirror, precision optics, of F5 or better and certified, are roughly $1600. Yet many websites sell Chinese imported mirrors, at prices between $500 and $800. Will the quality of the primary make a huge amount of difference in the finished product, or would investing in a better eyepiece yield the same results?
