I took the modified Jupiter-8 to the Udvar Hazy today, with a light yellow filter. This lens is RF coupled to 0.65m, which required removing an internal stop, "misthreading" the helical, and moving the rear module in closer to the front to reduce the focal length, then change the shim. Focus is good through to infinity. All shots at F2.

The Fortran code generates a 14-bit to 16-bit look-up-table using a Gamma curve, the extra 2-bits prevents collisions as the linear pixels are translated with the Gamma function.
