Lovely image Diego - great star colours too. :D
A tad noisy on the high res version (https://www.astrobin.com/full/325040/0/)?
Very nicely done - where did you take that one from? :thumbsup:

thanks Andy, this is part of my learning curve trying to get star color from my backyard......

no calibration frames and yes i have fixed the noise but haven't uploaded the result....

i am happy with my star colors now......

considering the light pollution conditions i have here.... :rofl:

Beautiful shot. Love the off centre composition and the star colours. Very natural looking.

Hi Diego,

It seems like a good result in spite of any light pollution. Great Image BTW :thumbsup:
