Description

Maybe one of the most challenging image processing I experienced so far...
Diging up details on NGC 3077 without burning out the cores of M 81 and M 82 required blending several stretch levels together; also playing with HDRMT at different scales helped bring out details (or not loosing them).
Anyway, thanks for looking.
