Blocking filter comparision : PST Bf Vs Omega Optical 394nm filter

This comparision has been cropped and the vignetting of the PST's BF isn't visible and the mentioned alignment of the Omega filter isn't obvious either, but it shows the contrast differences. (same proc. throughout)

0.00s full exif

other sizes: small medium original auto
