So I was unsure last night, so a quick forum search found these:
So I took that as no problem go for it, I’ll use this as reference if machine breaks and I need a warranty repair…(probably wouldn’t work as an argument, but in my head after a glass with the wife it did).
So I figured from the above and a few other posts it wouldn’t break the machine. So the other question is, is it worth ruining material. Since each mirror was 0.50$ each that fell into my “shrug, screw it, what’s worse that can happen” range of experimentation.
When I get time I plan to dicker with the defocusing.
