Description

Upper left = Ha

Upper right = S2

Lower left = O3

Lower right = combined image

I haven't found many images of this target taken with an Sii filter. There is a signal, but it is much weaker than the Ha. I took S2 binned 2x2 and had some problems with my calibration files. S2 does add some to the image, especially in the outer shell region.
