Re: [ATM] undercorrecting?
This was what I thought too. But if it's true that many (at least commercial) mirrors are undercorrected, the effect maybe doesn't show up, because the radiation doesn't make them overcorrected but just a bit more undercorrected then they actually are.

Seems to me that there are simply too many variables involved here, thickness, mass, material, mounting, OTA design and orientation, speed of temp shift and in which direction. If the shifts are as large as the numbers you're showing then the effect should be easy to see and document via the star test. Tony -----
