Good point about a ronchi test Eric. If it's a very nicely figured mirror, it might be worth getting it recoated rather than replaced later on down the track. You know what it's like - hit & miss 'freak mirrors' when it comes to mass produced stuff..I'm sitting on a freak right now & it's called a 'mass produced C11 SCT'
