Astronomik CCD 12nm OIII

[jetstream]

I figured I would start a new thread on OIII's and I apologize to Gavster for swaying so far off topic in his thread.

I'm in the process of ordering an Astronomik CCD OIII @ 12nm fwhm and the shape of the published curve seems good, lets hope it snags both OIII lines nicely. I should be able to see if its close to the edges of the lines with my 8" f3.8 newt as it might blue shift it by a little less than a nanometer. It will be a great comparison to the f7.5 SW120ED, if the views offers the same contrast it might be well centered for us. My Lumicon OIII is excellent so a valid comparison with be made here too.

Anyone, feel free to discuss any filter specs and tech in this thread-it an open discussion on them.
