Ngc 6357- the guts of the Crab

Hi all,
getting further and further from good conditions as time
passes.
The Earth she's a changin'.


Any way,
this emission nebula is quite interesting with lots
of action happening.
With my fov, you won't see why it was nick named
'the Crab'.
I didn't bother with taking any red channel for the
compilation due to the weather deteriorating when
taking the colour. So it's a Lum/ Ha combine and Ha substituted for red with the green and blue channels for the rgb.
The moon was out when taking the blue channel so it is probably a little washed.

So a bit of artistic license here.
Overall though, it is an emission neb and the Ha/ red
wave length certainly dominates.
Here's a link to my front page....

Thanks for taking a look.

All the best
Rich
