I have both Baader, Astronomik and Astrodon. My Astronomiks are the earlier generation before they brought out the low reflection models.
I got OK colour from Baader (biased to the reds), pleasing with Astronomiks (but they are thin like 1mm and need spacers to be held in place with some filter wheels), Astrodon gave me best colours most easily every time. So Astrodon's are my standard filters.
Mike Sidonio uses Astronomiks and his images speak for themselves.
Astrodons are the most expensive as well which is a negative.
Greg.
