Description

Data collected over 2 nights with clear skies, but poor transparency due to water saturated atmosphere. The rig was literally running with dew on the 2nd night. The resulting huge halo around Gamma Cassiopeia was at (well beyond) the limit of my current processing skills. I tried a star mask but that didn't work so in the end I opted for a more straight forward process work flow.
