I love M51 and this is probably my favourite image i ever took, i already attempted to shoot M51 around a year ago and it turned out okay but back then i didn't have a uv ir cut filter, coma corrector, i had way worse guiding than i have now and didn't have the same processing skills as i have now.
Equipment:
Skywatcher 150p f/5
Proxisky UMI 17r mount
ZWO ASI585MC (uncooled)
IMX225 guiding cam
SV165 guide
Baader UV/IR cut filter
Bortle: 4
Stacked and processed in pixinsight aswell as kindly blurxed by @broken lichen
