Description

Narrowband images were combined using the Hubble palette (R: SII, G: Ha, B: OIII). Most of the processing was done in Pixinsight, minor adjustments in PS though. I'm not completely satisfied with the output. Due to haze and a lot of high clouds the images lack sharpness and detail. Especially the OIII and SII images suffer from these conditions.

That being said i post it anyway :-D

To increase sharpness and get a more noisefree luminance image, i extracted the CIE L* component from the SHO image and used PixelMath to blend it with the Ha image: 70% Ha + 30% SHO-Lum (Revision B). I further processed both images indipendently and finally used LRGB Combination to combine them.
