I have been doing some upgrades, and I still need a better static ground glass. Here is a sample of my latest test. Can any one recomend an awesome staic gg other than wax. I'm thinking Thorlabs or Optisigma GG.

Thorlabs has imperfections and swirling, I do not recommend them. If you use Optosigma it's recommended that you use two 1500 grit up against each other to eliminate the aerial image. Nikon D screen has minimal grain but only at open apertures and Beattie screen, from my understanding, is similar.

Thanks Ben, I know about Beetie and Nikon D but I need something pretty big. about 3.5 x 5 inches, or maybe not. Ill look into a nikon d screen
