Really nice, Martin!

You are revealing a lot of that swooping S-shaped dust lane, and some great blue highlights along the edge too. :D

Thanks Mike,
Shame about the cloud moving in , I was hoping for at least 4 hours or more. Would have improved SNR and exposed more fine detail on the ends
Still very pleased with the outcome

Clear Skies
Martin
