  Ken, you are where you are, It makes no sense to try to change the depth
if you are now polishing,
unless you have alot of time on your hands. It might take a little extra
time to figure and you will
probably need a coma corrector but many on the list have deep mirrors.
F-3.5 I don't know f-4 yes.
