Description

This is a reprocessing of data that I captured and posted several months ago. The original processing approach was SHO with a palette focussing on maximizing structural detail. In this version I attempted a "natural" palette using Steve Milne's pixel math formula. While I like the colors of this new approach, I am still drawn to the detailed structure revealed by the original palette and approach. What do you think? Version B is the original SHO approach.
