Description

My firends Philippe Lamothe and Dominique Lechevrel shared with me some SHO data of this nebula made with a 14" F/8 RC. 300 seconds exposures with a Moravian G2-4000. 56 Halpha, 12 SII and 19 OIII.

It is the first time that I process SHO data. I mixed it with my RGB picture to get the stars colored and a best luminance in the center.



First version is the luminance S+H+O, second one an SHO only image and the last one is SHO + RVB.
