Description

A clear sky window last night allowed me to capture some OIII data to add to the Ha for this rendering. I had to extract the stars and then combine Ha and OIII nostars images in PixelMath using my usual formula to get a decent starting point; for some reason combining the fully starred masters produced a very dark result. The image presented here does not show the red/blue balance typical of my SNR shots...not sure what's up with that. But it's interesting in any event.
