Description

I just have to go for the Andromeda Galaxy every year!  What a beautiful galaxy!  This time I again used the great astrograph Celestron RASA8 with ASI2600c camera.  I combined a traditional RGB series with a series of frames shot through Idas NBZ filter.  Ha and OII portions were then extracted using Astro Pixel Processor (APP), a software I an very pleased with.  I tried various processing techniques, but enden up with a version where a mild DeEmp-script has been used in PixInsight to reduce the number of stars. I am, however, uncertain if the saturation is too heavy?  Anyway, I am pleased with the result... enjoy...
