Haven't shot Andromeda in a while.
A classic for all time.
Shot over two nights.

Not bad, but the signal was overstretched and everything became noisy and gray.

There seems to be an issue with large stars. BXT?

Starnet doesn't remove large stars, and during most of the shooting, the atmosphere created halos around the stars.
There's room to work on the stretching, and in general, with processing, there's always more to learn))
Thanks
