Thanks for the jpeg examples in O3 and Ha as they offer a real concrete example of what the two filters can do to complement each other.
Sadly I will not see Tarantula Nebula again for a very long time unless I start to rent time at the deep south astrophotography sites but that is expensive. I did spend a lot of time soaking in that and gobs of other LMC objects visually last month. Very kewl skies down there.
I wonder if anyone has tried 3-filters where the third is Si2 (guess I will read the full thread next). To me the lines for Si and Ha are so close that I question if a colorspace mix using these three (along with O3) can really do justice to the colorspace.
Ordered the Astronomik O3 and Ha only a few weeks ago but too late
for a proper Orion imaging run. I plan on Veil and North American neb
with these filters in a few months. Am at +36 dec up north here.

Thanks for the kind words re my images.
There is an Astronomik 12nm SII EOS clip-in filter I would like to try eventually, but I've read that it's a bit of a lost cause on a DSLR for the reasons you stated - still I like to try these things out for myself (I was also advised not to try Ha or OIII filters with a DSLR, and that didn't turn out so bad!!
).
I've tried combining the Ha and OIII images to form a Synthetic RGB.
Ha=Red channel, OIII Green=Green Channel and OIII Blue=Blue Channel. I like the method, it produces quite visually striking results on some objects. Here's the Synthetic RGB of the Tarantula region using the 2 Ha/OIII images...
