First deep sky LRGB M51

About this image

My first LRGB deep sky image. Atik 414ex, ZWO LRGB filters & ED70 (f6) telescope. Captured with APT, processed in DSS & PS. 35 x 3min subs in each filter, dark, bias and flat corrected.

I have done DSLR deep sky in the past (a few years ago) but not mono CCD & LRGB. Not great processing the brighter stars have a blue halo that could do with some work, but I'm pleased for a first attempt at processing. I'll spend some more time playing with it when I get the time.
