Here's the Lagoon. I've done this before, but this time I tried it with the Duo filter on my OSC camera. Captured in dribs and drabs from early July - August. Totoal of about 15 hours. Finally got some time to process it.
Comments please, as I'm still trying to figure out how to attack these images. For this I split the RGB channels and treated them as pseudo-Halpha & OIII.
