Thanks Rodney, I have thought about getting a Bahtinov mask made up i really like the idea of them. Initially i was reluctant because i would have to keep taking the dew shield on and off, but then I thought, what about getting one custom laser cut out of acrylic to fit firmly inside the end of the dew shield? Might be difficult to do that though. I suppose a non-issue realistically taking the dew shield on and off occasionally. I have yet to try FWHM methods as well.
