We finally got some [SII], but the seeing/wind was less than optimal. OK, it was bad. However, I did use it with the H-a and [OIII] to "finish" the image. That's where the "star wars" started - trying to equalize between channels. Any suggestions as to further minimizing the star size would be most appreciated. (Maybe spend more time collimating and re-take on a calmer night?) This version adds ~40% layer of L to sharpen up the stars as described on the linked page. Anyway, I hope you like it, and thanks for looking.
