Description

This is a mosaic of two images taken from Bortle 6 skies in Perth, Western Australia.

I had originally shot this image in HOO, but discovered that I'd used the wrong Oiii filter (12nm instead of 6nm). I reshot the Oiii frames and added Sii frames to the original Ha I had aquired. Processing of the Oiii was difficult, as even at 6nm, the background sky gradient was problematic.
