Hmmm?..so, just how many people don't read posts properly...?

Looking at your result I wish I had done some OIII too as my image only shows the reflection from the blue and luminance filters. I like the blue intensity in your image, colour saturation and the contrast of the image. Well done.
Thanks Paul. As Mike S mentioned, we did try a whole night of OIII on this beast, and found only blackness. So what we are seeing here must be reflection nebulosity. I'm guessing that means that the object is either in a relatively low-energy environment (not so many super-hot stars), or that where there are super-hot stars, the gas is too dense.

Oops, I thought I read that Mike had captured OIII. I guess we all make that mistake sometimes.
