it is faint and I downplayed the Ha so the sulfur
and oxygen will show through
i need to shoot some flats still so some of that
green stuff may go away
the color assignment is the usual wavelength
ordered palette: sulfur -Red, hydrogen -Green, oxygen -Blue

Richard, that must be a faint one! I'm not real
sure how the colour assignments go (which filter is assigned to green I
mean) but there is a lot of faint green nebulosity down and right of
the main nebula. Do you know what causes that?

this is a faint one.
you all probably remember the "question mark
and the mysterians" image from a couple of weeks ago. Well this is taken
to its logical conclusion: I added the [SII] to it.
It has taken a lot of nights to accumulate
13.5 hours of exposure but finally I got it finished last
night.
this is 7 x 30 minutes Halpha, 8 x 30 minutes
[OIII] and 12 x 30 minutes [SII]
I still need to shoot some flats and will try
to get them done tonight when I get home from work.
