Whirlpool galaxy ( M51 ) - HaLRGB

 This is the first target I managed to image in Mundoor, Kerala. This is an elusive target to me as it lies very close to the western Ghats so the window was pretty limited and I was lucky to gather as much data as I could. I am still not happy with the processing as there appears to be gradients.
