Nice image, Sergio.  It's a difficult balancing act to represent both the galaxies and the IFN well.

Cheers,
Rick.

Thank you, Rick,
I found that M81 on itself being always a difficult object for color balancing, dynamic range compression, contrast.
I've had other issues as well, as this data were imaged in 3 nights during two months, so atmospheric conditions were obviously different. My concentration was mostly on enhancing the IFN visibility and it's structures.
