Description

First finished work from our DSNM team since June! This project spanned across the monsoon season as well as system services period; finally we are glad to put an end on it. I aim to create a red background with the H-alpha data, but then struggled a bit to bring the dark dusty cloud out in the center of the frame; also our color data suffers quite a bit from blue color separation, not making it easier...

All in all, a belated good-bye to Summer 2021
