Great image Richard.
The long exposure time certainly paid off. As you mention the sulfur
channel, do you have that channel as a separate image somewhere? I know
how M27 looks in Halpha and OIII, but I don't have a clue about SII.


Actually I would love to see all 3 separate to see how it composes.

Anyway

Great work Richard

If you have Photoshop or another image processing program that allows
you to see the RGB color planes of a color image then you already have
the separate images. Richard doesn't make a synthetic Luminosity image
so the data you want is there in his photos. The red plane is Sulfur,
the green hydrogen and blue oxygen in this photo. He used a different
palette for the Veil shot he posted. I've been told the free GIMP will
do this. I don't have it so can't verify that.
