Bubble Nebula in Narrowband (Posted 11-22-09)

I like this version the best, I think. This image was processed last. I am experimenting with Maxim DL and did an LRGB combines using the same data as the others below. Better?This is the finished narrowband Bubble Nebula, NGC 7635. The brightest star in the bubble has cleared the space around it with its strong stellar wind. The colors are mapped variously. The first image above has Ha as Green, OIII as Blue, and SII as Red.
