Having tried earlier to process M45 with meagre result I restarted with the same data set from TelescopeLive. About 25 hours of images from SPA-1 in Spain.
30 frames RGB @ 180 seconds and almost 150 frames LRGB @ 600 seconds.
My attempt is to maintain some true star colours and still see the glory of the Seven Sisters.
I processed using PixInsight the 30 shorter exposures with WBPP NSG Drizzle and NXT. Also added some more colours using HSV repair. This became the platform on which I added nebula structure obtained from the longer exposures. Same processing for the LRGB and in the end Starnet2. Some HDR processing and this image was then added to the base image with pixelmath.
Final adjustment in Curves Transformation and brushing up in Lightroom.
