Finally, this project is completed and so is this season (I hope not)... The LRGB version of M51 is here..Took me 5 nights (1 in April and 4 in May) to image the whole thing. And very long to process. Wish to add Ha but its been cloudy since a week and a storm expected this week.
And a tight crop

I have not been able to get the star cores and colors right. Tried using HSV Repair Script in PI but to no avail. Please help me out with that.
