Lovely image Diego - great star colours too.
A tad noisy on the high res version?
Very nicely done - where did you take that one from?

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....

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

Hi Diego,

If I'm not being too nosey, which Melbourne suburb was that from?

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

Best
