Description

Bad weather is still above our heads in Paris, so I continue to reprocess older datas with improved skills in data processing and Pixinsight.

I made a very greenish version of PacMan, in SHO, and I wanted to make something closer to what you can observe in continuous spectrum, with H and S in the red channel and O in blue and green.

Plus some better data processing (32 bits, estimation of the PSF and deconvolution etc...).

I hope these progresses are visibles !
