Member "fonakta" at that forum took some nice photos with the filter. Click on his profile to see his posts and photos.

I think off-set oblique + polarizers partially crossed can give you better images. Good microscope polarizers are not cheap though. The GUF filter is much cheaper and easier to DIY install.

Hey 75,

Thanks for the reminder, I had some of these printed out and waiting for me to cut them out and try them for months now. Time to dig them out.
