Quote: I assume the lack of response to my question, "Has anyone run an FFT on the Bahtinov mask?" means nobody has - correct?
Would you all please take a look at Forum Article #27 on my website <http://www.brayebrookobservatory.org/BrayObsWebSite/HOMEPAGE/Forum.html#TOP>
great article chris thanks for posting it! why don't you submit it as a formal review to cloudy nights?
fwiw, i confirmed empirically that my B mask focal point doesn't shift when it's moved off axis. others have reported results similar to the B mask with a y made out of fishing wire, so this brings it together nicely.
perhaps the lord-y mask should work especially well on sundays
