Someone will come along shortly with some Maths and maybe some charts and optical info but that covers it pretty well I think  |
That is just wrong, have you read anything about how GSO mirrors ( which are Taiwanese actually) are made these days and the quality they are delivering. If Bill is thinking of building his scope, GSO mirrors are the most cost effective/quality on the market. Certainly, don't buy mirrors off Aliexpress from unknown sources. If you buy GSO mirrors from Bintel you always have the option of returning it if its rubbish, but it won't be.
