Description

This is a reprocessing of data I collected in September 2018. In this version I used a different palette to reveal more detail, and cropped to alter the composition. The clouds and fog have been relentless in on the Northern California coast. Thank goodness I never delete any data so I can continue to feed my astrophotography obsession.
